I recently upgraded from 2.9.5 to 2.10 and ever since I've been having an intermittent problem with email sent from within my web framework (Interchange - icdevgroup.org) not reaching its recipient. I usually get an error message in Interchange's log when there's a postfix problem but not with this latest issue. I know this is incredibly vague, but can anyone hazard a guess as to what the problem might be?
The big config change I see referenced with regard to 2.10 is smtpd_relay_restrictions but I don't see how that could be related. My smtpd_relay_restrictions is blank. - Grant
