Re: [vchkpw] Qmail keeps failing!
Hello everyone, Here is the update on this crazy server issue which is leaning closer and closer to a case of SFA (stupid flippn' administrator). My server appears to be running daemontools ok. I need to investigate daemontools more closely over the course of the day, but daemontools truly does not seem to be contributing to the problem or the solution (from what I can see). I can find no reference to this /env/CONCURRENCY directory on this system at all! Correct me if I am wrong, 1 My CONCURRENCIES are max-ing out and raising the limit is not the solution. 2 Qmail, VPopmail, and QMail scanner are respawning 3 Each spawn will eat a few CONCURRENCIES? 4 Editing evn variables won't prevent the respawning? So it would appear that this knucklehead administrator has to find out why this thing is respawning all the time and that should solve the core issue of this "qmail keeps failing" issue. Pointers? Suggestions? Albert Einstein, The most difficult problems have the simplest solutions! Brad Sumrall
RE: [vchkpw] Qmail keeps failing!
Brad, Turn on debugging in qmail-scanner. I believe you may find an answer there. That's the process that seems to be "hanging". I believe if you open qmail-scanner-queue.pl you'll find a line that starts with DEBUG and it's probably set to zero. Set it to one and you'll get more information in /var/spool/qmail-scanner (I think that's it .. been a while). Unless you're using some specific function of qmail-scanner that Simscan doesn't have, I would strongly recommend switching over to Simscan. It really reduced my server load and is much faster.

Re: [vchkpw] Qmail keeps failing!
Hello all! First off, I would truly like to thank all of the people who have responded to my post. Your level of support has been all so helpful. Everyone that has passed my emailhas beeninvestigated deeply. The best part is that I have more question due to the enlightenment I now have, and a few suggestions for the developers. Quickly, my background is USMC and self taught training. My expertise is in routing / networks / and apps that support them. I have about 6 collage credits towards programming, so my c++ is very basic with many memory leaks etc...in my programs which is why I leave most of that to you guys (and girls!). So, as a knuckle head who stepped away from Microsoft about 3 years ago to Linux (gratefully), I think I am slightly past novice. So my questions are very legit for the typical admin embracing QMail. Quick follow up because most of the previous emails have been chopped from the replies. My original problem was qmail failing. After a day or so or less, outgoing emails would not make it out. Our typical mail program is MS Outlook. (Yes, I know, MS sucks, but preferred with my customers). MS Outlook would just sit there and time out on an outgoing email request. A gentlemen pointed out he my CONCURRENCY limits were max-ing out. They were set to 30 for an office of about 23 workstations (makes sense because Microsoft does not like to let go of stuff). I set the limits to the max. Ok, someone pointed out that this was not a good idea unless I wanted my server to come to it's knees due to a memory flood. I began to see this response and switched it to 115. Ok, it seems to be doing ok now, but... (yes, all can criticize me on this, but the situation merits it right now) This server right now is also being used as a master file server for engineering data. This 115 might very well shoot me in the foot very soon due to load issues I was told to disable spamassasin for out going emails. (good point but how?) Or disable it all together (can't, this IP was identified and a prime spam source when MS Exchange was running the email (go figure, someone hacked Exchange 2003). I just had a gentleman refer to a -c flag adjustment (Dude, chu wanna come work for me? You are on a level way above me. Keep up the good work!) I followed the QMailRocks installation to the "t" for this Qmail installation. Ok, the nuts and bolts, I can find no indication that I am scanning outgoing email at all, in the Qmail scanner. How do I find/verify and disable? What are the key apps I should launch to see what or who has control in qmail issues and why (i am aware of the obvious /var/log/ and netstat and ps and the other very basics.) What are the recommendations to tune this system correctly (this is a new install and 3rd qmail install for myself)\ Suggestion for the developers A simple question during configure for the expected number of users...

On Thursday, July 7 at 09:18 PM, quoth [EMAIL PROTECTED]:
I was told to disable spamassasin for out going emails. (good point
but how?)
Depends on how you have it all set up. I understand you use
qmail-scanner? Basically, you want to unset QMAILQUEUE whenever
RELAYCLIENT is set. The easiest way is to add a shell script to your run
file. The basic run file looks like this:
tcpserver ${TCPSERVER_OPTIONS} qmail-smtpd
So change it to:
tcpserver ${TCPSERVER_OPTIONS} nospamforrelay.sh qmail-smtpd
Where nospamforrelay.sh is a shell script that looks like this:
#!/bin/sh
test `printenv | grep RELAYCLIENT` unset QMAILQUEUE
exec $*
Or disable it all together (can't, this IP was identified and a prime
spam source when MS Exchange was running the email (go figure,
someone hacked Exchange 2003).
What's that got to do with spam filtering for outgoing email?
I can find no indication that I am scanning outgoing email at all, in
the Qmail scanner.
Because that's not qmail-scanner's purview. Check out The Big Qmail
Picture to familiarize yourself with how things work
(http://www.nrg4u.com/). Qmail-scanner gets stuck between qmail-smtpd
and qmail-queue, depending on the contents of the QMAILQUEUE environment
variable.
How do I find/verify and disable?
Does outbound email get tagged with X-Spam-Status headers? If so, then
you're scanning them unnecessarily. If not, then you're all set.
What are the key apps I should launch to see what or who has control
in qmail issues and why (i am aware of the obvious /var/log/ and
netstat and ps and the other very basics.)

RE: [vchkpw] Qmail keeps failing!
Brad, If you need some help contact me off list. I'd be more than happy to donate an hour or so to help you get going. A little advice. I hate stepping on the hard work of others but this isn't the first time I've heard of problems with the Qmail Rocks instructions. Follow Bill Shupp's toaster instructions of Life With Qmail and you shouldn't have any problems. Here's how I do my installations. Usually takes me two to three hours total depending on how many brain-farts I have :) and how fast the Internet connection is. I usually just download everything as I need it. I use Mandrake so I urpmi stuff as needed as well. You sound small enough that you probably don't need to use MySQL or PostgreSQL. I use PostgreSQL personally. If you are going to store your users in a database then you'll need to have that all installed prior to starting the process. install qmail with no patches install vpopmail patch qmail with Bill Shupp's toaster patch and custom patch reinstall qmail install clamav install razor-agents install spamassassin install ripmime install simscan install daemontools install ucspi install maildrop install courier-auth install courier-imap install squirrelmail I think that's about it. I'm sure I had a lapse in memory somewhere. I have BGP on the brain right now! :). The order should be about right too. I'm sure someone here will let me know if I missed anything. :) For your size of office, I'd say a concurrency of 20 should be sufficient. Looking back to your process list, it appears you have some process that's hanging and causing you to have too many concurrent connections. I run a small ISP with about 1500 addresses on my server. I run my concurrency max at 100 but rarely see over 10 to 20 connections. My max today was close to 40. That's both inbound and outbound SMTP connections. Using simscan, I scan every message using SpamAssassin and ClamAV and don't have concurrency issues. Hope you find this information useful.

First off, I would truly like to thank all of the people who have responded to my post. Your level of support has been all so helpful. Everyone that has passed my emailhas beeninvestigated deeply. The best part is that I have more question due to the enlightenment I now have, and a few suggestions for the developers. Quickly, my background is USMC and self taught training. My expertise is in routing / networks / and apps that support them. I have about 6 collage credits towards programming, so my c++ is very basic with many memory leaks etc...in my programs which is why I leave most of that to you guys (and girls!). So, as a knuckle head who stepped away from Microsoft about 3 years ago to Linux (gratefully), I think I am slightly past novice. So my questions are very legit for the typical admin embracing QMail. Quick follow up because most of the previous emails have been chopped from the replies. My original problem was qmail failing. After a day or so or less, outgoing emails would not make it out. Our typical mail program is MS Outlook. (Yes, I know, MS sucks, but preferred with my customers). MS Outlook would just sit there and time out on an outgoing email request. A gentlemen pointed out he my CONCURRENCY limits were max-ing out. They were set to 30 for an office of about 23 workstations (makes sense because Microsoft does not like to let go of stuff). I set the limits to the max. Ok, someone pointed out that this was not a good idea unless I wanted my server to come to it's knees due to a memory flood. I began to see this response and switched it to 115. Ok, it seems to be doing ok now, but... (yes, all can criticize me on this, but the situation merits it right now) This server right now is also being used as a master file server for engineering data. This 115 might very well shoot me in the foot very soon due to load issues I was told to disable spamassasin for out going emails. (good point but how?) Or disable it all together (can't, this IP was identified and a prime spam source when MS Exchange was running the email (go figure, someone hacked Exchange 2003). I just had a gentleman refer to a -c flag adjustment (Dude, chu wanna come work for me? You are on a level way above me. Keep up the good work!) I followed the QMailRocks installation to the "t" for this Qmail installation. Ok, the nuts and bolts, I can find no indication that I am scanning outgoing email at all, in the Qmail scanner. How do I find/verify and disable? What are the key apps I should launch to see what or who has contro

Re: [vchkpw] Qmail keeps failing!
Sending an email from outlook will "time out"! It will just sit there and stare at us trying to send, and nothing happens but a "session timed out" error. Brad
