RE: [vchkpw] POP3 authentication - erratic vmysql auth problem - self solved
On a new linux mailserver I was having an erratic problem with mysql and pop3 authentication. Authentication works 90+% of the time. However, using The Bat! and Outlook clients, I randomly see the following authentication failure and the user must poll pop3 again - which then succeeds. SOLUTION: In spite of what the qmailctl stat told me, I found that increasing the pop3 'run' file memory limit from 800 to 1200 appears to suppress this issue. Any thoughts on why would be welcome. Otherwise, one for the archives... Thanks! Dave. aside from 'the bat!' being a spamware client filtered by most mail daemons and spam solutions... on inbound mailservers... your clients are probably sending/reciving bigger spam attachments than normal to longer lists... u might also want to look at the number of cc's and bcc's those clients are sending... and if its inbound pop have you looked at the size of the pop mailboxes that they are attempting to check? a good hit with 3 or 4 heavy emails will blow 8m pretty easy... remmember the mem limit is the size of the pop binaries \PLUS the mailbox size kenneth gf brown ceo shadowplay.net

Hi, The actual service didn't crash, tcpserver is always running. qmail-popup or the actual qmail-pop3d crashed with a lack of memory. tcpserver and qmail-pop3d are two different things. Regards, Rick
