I am running a server FreeBSD 8.1, IPFW with Postfix, Dovecot, amavisd-new... I am having issues with some, not all, incoming mail from several providers, primarily gmail and mindspring.com. The error message that was provided to a user was along the lines of:
The maillog shows no information relative to the un-accepted requests. I have started trying to one through tcpdump but unfortunately none of my gmail accounts are subject to this problem.
I have tried to address this on postfix list as I thought it was appropriate as some mail made it through from gmail and some doesn't. I have been informed, besides in their opinion I shouldn't be attempting to administer a server, that this is not a POSTFIX problems as there are no problems in the maillog and therefore it must be an OS issue.
IPFW has port 25 open and the problem continues even if I turn IPFW off. So it would not appear to be a firewall issue.
It would appear that I need to record tcpdump to files and hope to catch the bounce there.
Can anyone provide any other suggestions?
