Installing big-concurrency.patch
Hi, What's the correct procedure for installing the big-concurrency patch on a live system? Is it just a patch, make, make setup check, restart qmail? Or will it affect/break anything else? Thanks, Brian -- Brian Baquiran <[EMAIL PROTECTED]> http://www.baquiran.com/ AIM: bbaquiran Work: (632)718 Home: (632)9227123
qmail initiating identd lookups?
Is there any component of qmail/ucspi-tcp that would initiate identd lookups on a remote host? A network admin has complained that his server has been receiving a large amount of identd queries to his server coming from our mailserver. Here's the excerpt from the logfile he sent us. 210.16.71.2 is our mailserver.

A little tweaking with 'ulimit' might help, or > perhaps you need to tune your kernel somewhere deeper. For Linux, you need to increase NR_TASKS. Edit your /usr/src/linux/includes/linux/tasks.h and recompile the kernel. I've already bumped up NR_TASKS to 1024, then again to 2048. From the comments in tasks.h, the limit for NR_TASKS is 4096 on intel, but I haven't been able to get it to boot when set to 4096 (this is on 2.2.14, IIRC, so newer/development kernels may be different.)

Nobody's worried about the mail system being overloaded (bandwidth now becoming the limiting factor). It keeps The Man off my back. IMHO, a small price to pay. Of course, yes, it could be handled by a PII for now, but I'd still rather have the quad Xeon with the redundant hardware goodies (and a service contract) than an off-the-shelf PII, or even one built by my own hands. > > Although I'm not familiar with the intricacies of how load is > > distributed across multiple CPUs among different OS's, I would suspect > > something is wrong with your system. > > That is an absolutely terrible thing to say.

From my limited experience, and our record of loadaverages over the past 3.5 weeks, a load average of 1.4 would indicate something out of the ordinary. > (and obviously, not enough about Unix or computers in general) to > make an accurate analysis based on his post.

I manage a similar system (quad Xeon, 1GB memory) with a loadaverage of 0.3 or thereabouts. Although I'm not familiar with the intricacies of how load is distributed across multiple CPUs among different OS's, I would suspect something is wrong with your system.

I happen to like vpopmail (http://www.inter7.com/vpopmail), but then again I'm only managing one large domain. It has optional MySQL support, and has commands to add/delete users and domains, change passwords etc., and has support for user quotas.

Otherwise, it's a stock LWQ installation. Oops. Actually, it WAS a completely standard LWQ installation. I had forgotten to restart qmail-send, so it was using the concurrencyremote default of 20. I restarted qmail-send, and watched qmail-qstat report a rapidly dwindling queue. It's back to normal now. I also watched my load average shoot up to 2.5 as all the qmail-remote processes fired up.

How big is a big queue?
Hi, I'm currently managing a mailserver for a service with around 5500 virtual users as of this writing, and we get over 1000 new users daily. I've been tracking our queue size since we launched, and it's currently just shy of 1000 messages, with ~650 messages unprocessed. Is this going to be a problem? How big are queues supposed to be? Also, I've lowered my queuelifetime to 2 days and increased concurrencyremote to 120. Otherwise, it's a stock LWQ installation. Any helpful tips, patches, etc. would be very much appreciated.

The default vpopmail installation does not bounce mail back to the sender if he tries to send to a non-existent user. Instead, the mail goes to the postmaster account. To change this, you should edit your ~vpopmail/domains//.qmail-default file, and put bounce-no-mailbox instead of the postmaster directory as a parameter to vdelivermail.

You probably should use something like vpopmail (http://www.inter7.com/vpopmail) which does this. The current version has support for MySQL.
