Re: [vchkpw] Qmail with Simscan, SA and ClamAv

I recently installed simscan, Spamassassin and ClamAv. It all works really well, but during peak hours (say 300 to 500k per sec inbound traffic) Thee server starts to bog down and progressively gets slower and slower until 120 connections are maxed out and the server starts rejecting smtp connections first and then pop connections. This is a new AMD 64 bit with 1Gig Ram running on Debian and running also Apache with php, mysql, and Horde webmail (with very very few hits per day). If I turn off simscan, situation returns to normal after a while. I have tried finding some documentation about how many users and traffic qmail with simscan, SA and Clam may handle, but it seems there is nothing out there other than very general stuff like many users, thousands of users Perhaps the problem is in my setup and some configuration for simscan, SA or clam that I have set/not set incorrectly, ot I have not realized this number of users and trafffic is just too much for one server. Any suggestions or links to appropriate docs will be most appreciated. Thanks! Max Esquivel I was having a similar issue. For my environment it was being caused by large attachments. I ended up only using simscan to call clamav and set some basic attachment blocking policy. I call SpamAssassin through procmail, but only on messages smaller than 250k to avoid scanning large media attachments. I also get user_prefs working this way. I still haven't figured out hot to get user prefs to work on aliases though. :( .darrel.

I've got too much tied to vpopmail. Which bit of the mail server do you want to change? And why? I think you'll struggle to remove the local delivery part as vpopmail is pretty much tied to qmail, but you could always use a different smtp server as a front end to a system running qmail internally. Personally, I run qmail/vpopmail with qpsmtpd as the smtpd server. R. The whole shoot and shebang. It seems the powers that be have decided that Qmail is 'unmaintained', and no longer consider it a viable option for our businesses' long term needs. I don't have any say in this unfortunately. I just get to plan and execute the migration. .darrel.

I've got too much tied to vpopmail. You can inject mails from postfix one at a time into qmail and then qmail will send it the normal way. Or you get yourself a delivery agent that understands vpopmail or dot-qmail... I'm less concerned about the smtp end of the equation. I'm more interested in the deliver half of the equation. After all that is what vpopmail plays a part in, and that is the part of the system I hope to keep. I do radius and ftp authentication against it. Currently I use vpopmail with mysql. I'm thinking I can use the vpopmail table for delivery from postfix. I was wondering if anyone else had attempted it yet. It seems like it would be an easy thing to do...

And to do that, he should be improving upon it - that is, accepting at least the patches that we all use. Obviously it's not a complete product, unless you can point me to a substantial 'stock qmail' userbase. Nobody can even provide binaries for the 'lessers' among us - so they will never use it. my rant These couple lines are the crux of the problem for my higher ups. They feel that there is not central driving force behind qmail on a fast moving internet. It lacks user and general support base. It doesn't come with our linux distribution, and it can't receive support from packagers. If they want qmail support its one more vendor in the loop. I've got to interface with the business guys. Qmail's licensing is prohibitive to it's long term viability and Dan Bernstein will drive his own software out of existence by not being a responsible maintainer. I believe he wants it this way. 5 nay 10 years ago almost... qmail was the bomb sniggety in a world of defunct sendmails. It was fast, efficient, and simple to administer. Now it shows its age. It's apparent that it isn't well maintained except for a community that strongly believes in it, and for good reason. The problems with qmail are not technical, they're political. /myrant ne ways, I have to migrate away from my beloved qmail. I'm not too happy about it.

I was waiting until we got our site migrated to our new colocation provider. http://www.inter7.com/vpopmail/vpopmail-5.5.1.tar.gz Or from the vhostadmin page: http://www.inter7.com/vhostadmin/vpopmail-5.5.3.tar.gz The difference between the two is the 5.5.3 has development vpopmaild code. The plan is to integrate the spamassassin code into the production version. Anyone want to work on that? Ken Jones ack. migration. I hate those.. I'm probably going to be doing that next month.. The quest for more bandwidth less money. :). integrate the spamassassin code into 5.4? I may be able to work on it this weekend, I have to finish up some web development for the remainder of the week, but I need to modify it anyway to work with my spamassassin plug-ins. .darrel.

As I understand it (also how my setup works), the usual way is to change qmail's deliverer to qmail-scanner.pl, which works with spamassassin and clamav, among others. James Longstreet Until about a year ago I was using qmail-scanner. It was killing my mail servers. I'm trying to get as much cruft out of my mail system as possible at the moment. I currently have a setup that uses rblsmtp + chkusr + simscan/clamav to handle virus/spam/attachment blocking at the smtp level. Then at delivery I'm using procmail to run spamc to per-user spamassassin settings working. I am hoping to pull procmail out of the mix and stick to just vdelivermail.
