Hi, We have been asked to consider using a set of 6 Postfix servers to provide a buffer between Exchange and our Compliance Archive servers, as follows: . Normally Exchange will route directly to the archive servers, but can route via Postfix if required. . If all the archive servers are down f

Sender Rewrite Scheme : bounce back to the original sender

Hello, Some of our users are using forward to get a copy of their emails in a third party mailbox (gmail, yahoo, …). That’s why I have implemented the Sender Rewrite Scheme to be SPF compliant in that case. But the solution I have is actually half working and I have some problem when he final d

smtp_tls_security_level = may with Exchange

Hello, with postfix 2.9.6-2 I'm using smtp_tls_security_level = may. No problems with it, but sending mails to some Exchange servers I see this error: *lost connection with mail.domain.com [...] while sending MAIL FROM* If I try to send a mail from bash using: openssl s_cl

rewrite milter result DISCARD to REJECT

error_limits fine tuning

Hello, I am wondering why the default error limits in Postfix are set so high: smtpd_soft_error_limit (default: 10) smtpd_hard_error_limit (default: 20) I have changed them to "3" and "${stress?1}${stress:5}" respectively, and my servers is still being flooded with "relay access denied".
