Subject: Re: discrepancy with # of messages

Hi.
Just as a hint:
when testing the late betas, I encountered the same problem.
It only appeared when users got bulletins: the messages were "mangled", put
in one big message. 
So a telnet showed 1 message when actually there were like seven or so.

After some testing, I blamed it to the client (the Bat was in test),
because the prob never showed up with Eudora.
It seemed that the Bat 1.2 somehow mixed up the spool. No idea about the
mechanism.
So I skipped using the bat, and prob never showed up again.

Does this help in any way ?

I've tried it without shadow passwords.
Changed the permissions of /var/mail to the required permissions as
written in INSTALL and FAQ.

ls -ld /var/mail
drwxrwxrwt    2 root     mail         4096 Feb 16 12:11 /var/mail

When I telnet to port 110:

-ERR [SYS/PERM] Temporary drop /var/mail/.sander.pop not owned by
sander.
+OK Pop server at www1 signing off.

The file /var/mail/.sander.pop is created, but with the wrong
permissions:

ls -las .sander.pop
0 -rw-------    1 nobody   nogroup         0 Feb 16 12:11 .sander.pop

Any suggestions ?

Looks like you have wrong permissions on /var/mail.  Here is what I have:

kemper:~$ ls -ld /var/mail
drwxrwsr-x    3 root     mail         4096 Jan 26 21:43 /var/mail

I have gone the 'easy' way.

Downloaded gnu-pop3d. Worked in 10 minutes (with shadow passwords).

I am having clients report that while checking their mail on Eudora, I
believe, that it starts to download their mail, then it stops and gives a
"FLUSH" error.  Does anyone know what this means or why it could be
happening?  I am using qpopper3.0.2.

I recommend upgrading to Qpopper 3.1.2.  If the problem happens 
again, please try to get detailed error information from the client, 
and check the logs for any errors around the time.

Okay. Take a look in your shadow file and check the
entry for your user. If it starts with a $ and it's a
really long hash, you're most certainly using MD5
passwords. If not, if there's no $ in the beggining
and it's a small (13 chars), it's a DES password.

Good luck with it! I'm still waiting for someone from
Qualcomm to give us some feedback, if possible.

Qpopper should work with md5 passwords if PAM is used.  I'm also 
looking into adding support for md5 passwords without PAM.

Don¥t you mean "Qpopper should work with DES passwords
if PAM is used?" and "I¥m also looking for adding
support for DES passwords without PAM?". Because it
already works (and pretty well) with shadow + MD5. Our
problem seems to be shadow + DES passwords without PAM
(as you mentioned, it works if you use PAM).

And thanks for the quick response. :)

The machine is using DES password encryption.
Does that mean it should work straight away ?

Hi,
 Lately I have installed qpopper on a simple testing server. But then I have
a problem. It didn't work properly. When I try to connect to it, it will
quickly disconnects me(Tested by using telnet <ip> 110 /telnet <ip> 995).
The testing server is a pentium pro on RH7. Qpopper is called by xinetd

Is anything being written to any of your logs?

If you have an error in /var/spool/mail/config/qpopper.config, 
Qpopper writes an error message and exits (it writes the message to 
stdout, so if you telnet in you see the error).

Either Qpopper isn't being run by xinetd because of some 
configuration problem, or Qpopper is being run but is unable to 
continue.

See <http://www.eudora.com/qpopper/faq.html#certs>.  Note that the 
instructions are for Qpopper LX.

You download it, run './configure' with any desired options, run

ISTM that these are all MUA [client] dependent.  However, once it hits
the mailing list server, the mailing list software may have its own
policies that it implements, changing your best desired plans.

FYI, all I did was hit 'g' and the reply addresses went where you
wanted them to.

You might want to try using 'mutt' instead of Messenger.  ;-)

Hi,

we happened to slip into a situation (which I personally don't really like,
though it's actually an interesting challenge) - however, here we are - and
I know, that this is only 1/2 correct place to ask for (and also been
looking the archives up and down...).

Anyways:
We have to get a mail environment up and running ASAP.

	* currently 600.000 emails per day
	* 200.000 users/email addresses, single domain environment
	* the system must be scalable to support 800.000 users
	* authentication/lookup via some sort of db (not decided which yet)

- I personally feel Exim to be the right decision on the SMTP side of
things.
- I don't really feel comfortable with the POP3 side yet. Qpopper? Is
Qpopper LX really that much better? However, Qpopper is the only POP3 server
I can *really* talk about...

to get back to topic:
I'm completly lost with the Hardware thingy... (ever talked to a salesman,
asking for some sort of advice from that company, and all he comes up with
is "no problem, Sun Server, Storage System, Giga-everything. ...hrm, lets
say 8.000.000 US$. when do you want to sign?") grrrr.....


Does anyone have any experience with this, or have any hints, where to look?
Any sorts of hints are more than welcome... and I'd probably also pay for
it... (no, I wouldn't the budget is too low ;) )

well, obviously I'd prefer the *free* option ;) so... all sorts of hints and
advice is very, very welcome!


Thanks very much in advance for your help!

	Assuming that you dont follow Evans' 3rd law:

	I don't like solving other people's problems for free, so I will
	just give some pointers as to how to go about it.

	Requirements:
		1 domain, 200k MBX, 600kmail/day. 

	First thing you have to lose the "single box" and "/etc/passwd"
	mentality.  Once you start thinking "distributed systems" and
	"there are no lusers, there is only mail" you are on the right track.


	You have a stack of machines, in a front/back configuration.
	

	FRONTSIDE:

	The front end machines are all identical HW/OS (freebsd is nice)
	Because they are identical, you can shift them around as you overload services.
	All machines have 2 interfaces, one outside, one inside.

	Group 1:  INCOMING MAIL  "mx01/2/3/4 ad nauseum"
		They receive mail, and use EXIM/LDAP mail routing to shunt it to
		the back ends.

		EXIM-LDAP (www.exim.org)

	Group 2:  POP PROXY  "pp01/2/3/4/ ad nauseum"
		They receive a pop connection, get the Username and route the connection
		to  the back end machine.
		
		PP-LDAP [1] (no url, this code isnt ready for the public)

	Group 3: (OPTIONAL)  OUTGOING MAIL "smtp01/2/3 ..."
		If you are a responsible ISP, you force your lusers to use your mail servers
		(so you can track and kill spammers) 

		EXIM

	Group 4: (OPTIONAL) RADIUS
		yes, you can do all your dialup authentication with the same database ^_^!
		
		FREERADIUS (www.freeradius.org ?)

	Group 5: DNS
		when youre a busy mail system, you need rock-solid resolvers. Make sure you
		have a couple of dedicated boxes for this.


	If you must use linux, firewall the hell out of it. 


	BACKSIDE:

	Backends have no direct internet capability. If they send mail out, they use the
	SMTP servers in front.

	Group 1: MAILBOX MACHINES "mb01/2/3/ ..."
		They receive mail with Exim and drop it into mailboxes, quota MUST be enforced
		here, or you'll have morons wiht 900Mb mailboxes and that sucks for POP.

		Hardware raid, Disk IO will be your be all and end all here. logging filesystem
		if your OS of choice has it.

		EXIM

		QPOPPER-LDAP [1]  (3.1 with ldap hacks)

		HOUSEKEEPER   (to stop the mailboxes filling up with dead accounts)
		

	Group 2: DATABASE MACHINES
		Studly hardware, at least 2, identical. Oracle db2 (postgres if you want, 
		this part absolutely has to survive, because if you corrupt your DB, you're
		in deep trouble. 

		DATABASE OF CHOICE
		
		Custom perl hacks to extract data and format it suitable for the LDAP servers.
		(Radius too if youre bored)  perl DBI


	Group 3: LDAP  (same as the frontside boxes)
		Everything is run by an LDAP server (openldap) it contains records like:

		dn: uid=bunny at gol dot com, ou=mail, dc=gol, dc=com
		objectClass: inetLocalMailRecipient
		mailLocalAddress: bunny at gol dot com
		mailRoutingAddress: bunny at mb07.farm.gol dot com
		mailPickup: bunny at mb07.farm.gol dot com
		userPassword: 230325FJJsqLM
		mailPath: /mail/spool/mb07.farm.gol.com/f0a/984/f3.bunny



	ANCILLARIES:
		logging server
		monitoring server 
		postmaster mail server

	TO THINK ABOUT:
		how do accounts get created?
		webserver inserting records into database.

		use oracle ldap and combine duties, then you get "instant" account creation.

		load balancing the front end (buy an arrowpoint and have it do that for you.)

		automatic distribution of mailboxes across backend servers.


	-------------------------------------------------
	Stick together with copious amounts of Fast Ethernet Switches, Stir gently and
	bake at Gas Mark 3 for 12 hours.

	I did all this once in 1999, and the second version was done by my replacement postie
	last year (debian/exim/openldap) with new hacks by yours truly.

	Before you run around screaming "thats like 14 machines!" you can start small.
	6 front and 4 back, combining database/ldap, putting dns on all the front boxes.

	As things melt, you throw more hardware at the job. the basic design is highly scaleable
	and in our case, runs on autopilot for the most part.
	

	This is roughly how Yahoo works too. Only they have a lot more distribution and big
	studly disk farms.

Hi,

I am relatively new to qpopper.  We are trying to use one server to do the
answering of pop requests and one to actually store the files.  They are
linked using NFS and are running on BSDI 4.1 and 4.2.  WHen I try and
collect mail the error is '-ERR [SYS/TEMP] flock:
'/var/mail/.win353827.pop': Operation not supported (45)'

BTW, the reason for doing it that way was to load balance the pop mail,
using 2 servers was just to test.

Does anyone have any ideas??

I appreciate your posting that. I'm only running a "tiny" server for a
few dozen people, so I've never gotten to see what a "real" mail system
looks like.

How do you distribute the load among the front end servers? Do you need
a special DNS setup for this? Or do you just hand out different server
names to different sets of users?

All recent versions of bind support round-robin.
Of course, in a large environment having an F5(BigIP) is always nice ;)

I would think clustering would be the key here.  

Some OS's support IP connectivity management.  DNS remains static, and the
machines negotiate for who is going to answer on a give port for a given
connection request.  If I remember correctly there is stuff built right
into RedHat Linux 6.2 and higher for this stuff.

His paper is as much a critique of current practices and what their

You could try doing it all on one server.  You might not have a 
problem, especially if you try Qpopper LX 
(<http://www.eudora.com/qpopper/>) which has some performance 
improvements.

If you do want to stay with NFS, you can try editing config.h after 
running ./configure and adding '#define NO_ATOMIC_OPEN 1'.  If you 
use Qpopper LX, you can use set the 'no-atomic-open' run-time 
option instead.  (Qpopper LX also has improved code in this area.) 
The intent of the NO_ATOMIC_OPEN code is to function over NFS. 
However, this has not been thoroughly tested, so it isn't 
recommended.

	If you have money, and want to blow 50000$ on F5 gear, do so. its
	just BSD with bells and whistles attached. (similar for arrowpoint,
	but as its now cisco, its probably more expensive.)

	The poor man's solution is to use dns magic. stick things in a 
	subdomain with a short timeout so you can remove/add from/to service
	with minimum interruption.

	One of my more entertaining scripts was one that started the appropriate
	services depending on the machine name.

		if my name is pp## then start popproxy
		else if I am an mx then start exim with this config, ...

	Another one was a housekeeper (house.pl) that walks directories and
	removes dead mailboxes (no such ID and over 48 hours old == dead)
	housekeeping can be a pain to do, but you mustn't forget it. ^_^!

866mhz, 256Meg of RAM and a MegaRAID array (amrd0) with qpopper
v3.0.2 in inetd mode compiled with servermode.  Some of my customers
get rather large emails (beyond 50 or 80meg each) making their
mailfile 150 or more.  When they go to check mail our load average
spikes from 0.09 to 7.?? and above sometimes as much as 20.?? or
30.?? if several people are doing this at once.  Also I have another
copy of qpopper compiled without servermode for use by our web-based
interface (Endymion MailMan) which also drives the load up even
higher when it copies the mailfile to the lockfile.

Any ideas? I don't think that someone checking a large mailfile
should bring my system to a screeching halt - when a certain user
(with an 89.4meg mailfile) checks her mail I get a page that POP3,
SMTP, FTP and DNS are down, as soon as she is done I get a page that
everything is up again.  During the downtime I can't connect via ssh,
if I am already in and watching a 'top' I see her popper as the
highest process and the load is up around 40 or so.

	When you open the mailbox from hell, qpopper scans the whole

	youre running through big mailboxes in a dumb string search, and
	you have several lusers doing this at the same time, 


	Possible cures: (not in order of sensibility)
	
		limit size of incoming mails aggressively. Mail isnt for

		use FTP.

		quota mailboxes aggressively. "for the greater good,"

		people who absolutely must have monster mails should be
		shovelled off to another machine so they wont inconvenience
		other users (and pay for the privilege.
		(if these are your own staff, require a budget for new mail

		qpopper 3.1, 
		xinetd

		distribute! distribute!

		shove a lot more memory in the box, read-cache the hell out
		of the raid

	And otehrs:

		kill off mailman, its a PoS. If you cant, force a mailbox

Subject: Re: large mail files, qpopper and high load on bsd

You sound I/O bound... Check the output of iostat (or the equivalent for
BSD if they don't have that... sar maybe??) Server mode, which you are
using, only saves on I/O when the user is either leaving all mail on the
server, or deleting all mail from the server for all other transaction
types, a temp drop file is written to disk. I think one cost effective
thing to try is to use the temp-drop-dir flag at compile to force it to
write it's temp files to another disk on a different controller. If
you're still I/O bound after that, I'd look into hashing the spool
directories and putting them on different disks/controllers as well.
More memory will also help buffer the filesystem. Don't let anyone sell
you more CPU, though, as the load average is high because it's waiting
on I/O. Of course there is also a lot of social engineering that would
help you as well... quotas, forced deletes, periodic purging...

Are you talking about slowness on the part of the client that is sending
the mail to your server?  If so, and if the client is Eudora, turn off the
option for "Use Mail-Exchange (MX) records" in the "Hosts" section of the
Settings.

For the record:  That is a sendmail question.  This is a qpopper list.

Remove the switch so you do reverse DNS like sendmail does, and things
are probably slow again.

I suggest to you that it is really a reverse DNS and/or allow filter rule
sendmail problem

Yet another reason why reverse DNS is important.

Qpopper LX 4.0 avoids this in many cases.  Session start-up with huge 
spools is usually reduced to sub-second response.  See

Subject: pop lock problem
Date: Tue, 13 Mar 2001 10:27:21 +0100

 Hi.

 We have congestion situation here on our network and pop sessions get
caught blocking the pop account (lock). I know why this happens and
lock's function.

 But what I want to know is:
- timeout value (the lock should be removed automatically after this
timeout) and how could I change this value. Is it necessary to
recompile?
- once the pop account is locked, does it affect the lock timeout if
the user keeps on trying to enter pop account? I read so, but this is
not logical, I think (from my point of view if the user enters new pop
session, it should be inmediately closed upon getting lock error).

 TIA.

For the MX frontends you may use DNS load balancing.
For the POP frontendes you may using a loadbalancing device like Alteon.

Hi,

In the Qpopper LX Manul is said:
"Qpopper LX offers faster session start-ups when using server mode. In may
cases session start-ups with very large spools can be reduced to a few
miliseconds from up to a minute (or even more)."

Anyone knows how Qpopper LX makes this faster session start-up ?
I know that in the session start-up, the qpopper reads all the mailbox
contents looking for the From headers.
How Qpopper LX advoids the reading of all the mailbox ?
Uses the Content-Length header for it ?

Greetings.

Try the -T flag.

Quoting the "INSTALL" doc:

-T timeout     You can change the compiled default for read 
               timeouts. This value causes qpopper to 
               terminate the connection with the client and 
               move the messages back to the user's maildrop
               if no input is received in this many seconds.

               The RFC states that this timeout should be 600 
               seconds (10 minutes). However, ideal settings 
               in many cases are between 30 and 120 seconds.

That's exactly the procedure.

	sticking with the free mentality for a bit, your pop proxys are
	clever, they know which user is on which backend server, so you
	can just round-robin them.

	one blows up, you either start up a spare on the same IP address
	or change your dns until you get it fixed.

Yes, but it is possible that you are running a different executable.

Try doing a 'make realclean'.  Then try to run Qpopper.  If you can 
run it, you have an old executable.  If you can't run it, then try 
'./configure' again, then 'make' and try it again.

This may sound like a really stupid question....but I am using Qpopper with
Postfix, and I was wondering if you can send out mail with Qpopper. We have
three machines networked together.. 2 windows & 1 linux, we also have another
person who checks his mail from home (another win machine). I can send mail to
any address using the lkinux machine (which has both programs installed on it),
but when I try to send mail to any other addres besides ours...such as
yahoo.com or anything at all, I get an error message. 

..one of the recipients was rejected by the server.

Is this something I have set up wrong? Did I write to the wrong list? Is it
possibly something I have set up wrong with Postfix.

Any help is, as always, greatly appreciated.

Thanks in advance,
