Re: [vchkpw] Vpopmail mysql and aborted clients
So then no matter for worrying about this? This can't break the database or... don't know cause any type of problem... or should I do any conf in authdaemon for this to be avoided? or is this normal and nothing happens with it? Thanks a lot!!! As told in other messages, the way of playing is different. Each vpopmail/qmail program usually executes brieftly and opens and closes MySQL, so there are no abnormal exits. When courier plays (both imap and pop), it asks auth data to courier's auth daemon. When this daemon is started, it opens MySQL and never closes it, as it supposes to reuse continuosly the same opened connection. But if none is going to use the connection for eigth hours, MySQL itself closes the connection. This will be opened again automatically by vpopmail library in courier's daemon, but you see an error in MySQL stats. Hope I've been clear.

Re: [vchkpw] Vpopmail mysql and aborted clients
If your courier still works without you need to restart it, it means you already have vpopmail in the right configuration, and you are only facing a log warning (which reason is now known).

Either restarted authdaemon if this happens or upgrade vpopmail. This should not break the database. It just affects your imap connections. Or change your my.cnf for mysql to allow unlimited timeout's. That's what I did (Well I actually set it to 4 days). Rick

Re: [vchkpw] qmail high performance
Hi Tren, Sorry. My english is not good :). My server is dual xeon 2.4 with 2 Gb RAM and HD SCSI 73 Gb. I have problems with delivery delay when my server is with many connections POP3 and SMTP. I use isoqlog to analyze my email traffic, but I don´t have stats of POP3 and connections with my SMTP (RBL, no delivery, ...). Exists any software to analyze POP3 and SMTP log? When my server is slow, I have: SMTP concurrent: 40 - 50 POP3 concurrent: 20 - 30 Load Average: 30 - 40 I have many SMTP connections with not existing recipient. My server was very good. Between last monday and last friday it is very slow. How can I identify a possible attack?
