There has been another question like this logged before, http://serverfault.com/questions/86315?tab=oldest#tab-top, however it was never really resolved.
I have multiple instances of postfix running on one server, which all generally seem to send perfectly. However i am occasionally getting the following error:
Nov 5 12:35:21 cp postfix-ms00/smtpd: connect from x.domain.com[xxx.xx.xx.xxx] Nov 5 12:35:21 cp postfix-ms00/smtpd: disconnect from x.domain.com[xxx.xx.xx.xxx]
Basically it connects and then disconnects immediately.
When i run tcpdump -s0 -X -i eth0 port 25 and host x.domain.com and the connect/disconnect error occurs nothing gets outputted.
Does anyone know how i can fix this?
is there a way i could watch the smtp command output? i.e: the "helo localhost" information when the mail is trying to be sent.
