Sendmail requires root privileges for some actions. Modern installations avoid being set root is by passing messages to sendmail daemon running with root privileges at 127.0.0.1:25.

Based on this fact, perhaps your problem was related to this KB: Why do I not receive mail I send to myself via a forward or mailing list? Gmail (and the gmail-based IU Umail ...

I'd recommend option 2 for just RAID 1 only. It's not really worth it to complicate your setup and double your chance of failure. Probably your best bet for improved performance would be to improve the rest of your hardware (though not an option you say). If your RAID0 fails, it will almost certainly just fail and not work at all. I can't really say what ...

As the restriction we setup matches only the domain (for the sender) someone was using our server as relay with with emails where sender was forged to match anything@example.com and would so be accepted. Yes, this is caused by this restriction in smtpd_recipient_restrictions check_sender_access ldap:/etc/postfix/ldap_restricted_senders.cf You said ...

Indeed, the solution is to inspect if the client auth configuration correctly match the postfix server auth configuration. In my case, postfix didn't enable authentication so I disabled authentication client-side and it worked. Question: why to downvote my question ? ...
