AW: AW: postfix - postgrey - lost connection after RSET
Thanks so far, the funny thing about the sending Mailserver is, that the MX for the domain in question is: forward : mail.bbb.com - ddd.dd.ddd.70 reverse : ddd.dd.ddd.70 - mail.bbb.com BUT the mail is delivered via ddd.dd.ddd.66 Might it be a problem of wrong NATing on their side?

Well, looks like spammer is connecting from ddd.dd.ddd.dd and after graylisting (45X temporary error) spammer software just drops connection. This depends if a...@aaa.de is missing a mail from b...@bbb.com and ddd.dd.ddd.dd is a valid mailserver for bbb.com then the problem is worth to investigate. Regards Andreas
postfix - postgrey - lost connection after RSET
Hiho, I'm using debian 4.0r6 / postfix / postgrey ... This works really fine for 99+% of emailsenders From time to time I get Nov 11 09:01:54 grey2 postfix/smtpd[28926]: lost connection after RSET from unknown[xxx.xxx.xxx.xxx] ... and users complaining about not being able to receive email from certain senders. I tried the following: grey2:~# telnet localhost 25 Trying 127.0.0.1... Connected to localhost.

Ask the users for the *sender* address and grep your logs for failed delievery attempts from this address. Regards Andreas
