I seem to be having issues with postfix on my server. It’s bouncing emails back to our clients at random. Meaning every once in a while some can get through. The system has worked fine since I started here in June '06. I didn’t change anything recently, and I’m the only one that would have. I’ve been reading on here the past few days and have tried some suggestions to no avail; I’m not sure where to go from here. I’d appreciate any help. Here is some of the information I’ve seen asked for in the related posts I’ve read so far. Sorry if it’s a lot, just want to give you as much info as I could. Running: Debian 3.1 (sarge) Postfix 2.1.5 MySQL 4.1.11 I have this excerpt from one of the emails that was bounced back: “This is a delivery status notification, automatically generated by MTA kvsmtp1.senders-domain.com on Wed, 28 Mar 2007 14:09:33 -0500 Regarding recipient(s) : [email protected] Delivery status : Failed. None of the mail servers for the destination domain has so far responded. (domain.com). We have been attempting delivery for 5 times. Maximum delivery tries attempted. Please contact your administrator to contact the destination domain or resend your message.” Last entries in mail.err log Jan 10 11:39:14 host postfix/smtpd[15635]: fatal: dict_open: unsupported dictionary type: pcre: Is the postfix-pcre package instal$ (this error repeats 20ish times) Jan 10 11:59:35 host postfix/trivial-rewrite[16649]: fatal: mysql:/etc/postfix/mysql-virtual_domains.cf(0,100): table lookup problem (this error repeats 10ish times) Jan 10 12:25:54 host pop3d-ssl: LOGIN FAILED, ip=[::ffff:65.16.81.99] Jan 10 12:26:40 host last message repeated 2 times (above two repeat twice) That’s the end of the mail errors, nothing else todate. Problem entries in mail.log (note this file is 185MB and ranges from 3-4-07 to 3-29-07. Can I save as mail.log.bak and start new mail.log?)

I actually had to cut out 86 TIME_WAIT lines from you see above to meet the max amount of characters allowed by a post. Is it normal to have that many? Would that be based on the server's traffic volume? Also the instances where you see “localhost.domai.” – that’s no typo for some reason it drops off the last few letters from the actual domain, it appears fine in other spots. Whats the reason for this? NOTE: Also I should point out I’m no system admin. I’m a programmer with only a small amount of Linux knowledge. I’m perfectly find getting around in the OS, but not quite clear on what process are doing what etc. Somehow the server admin role here has kind of been left up to me. TIA
Please run Code: postmap /etc/postfix/access /etc/init.d/postfix restart and see if the problem persists.
