[pfx] masquerade_domains does not work for relayed domain

Is it true that masquerade_domains does not work for header From: in relayed emails? I have a fairly generic setup: masquerade_classes = envelope_sender, header_sender, header_recipient masquerade_domains = mydomain.com that does indeed rewrite envelope from, but not header from, and

[pfx] Re: Unexpected behavior of regexp table in check_sender_access directive

The logging code lives outside the individual table drivers and with "_maps" parameters that support multiple tables, above any individual table lookup. Oh I see. Well without rearchitecting the logging it seems this could be made more intuitive for the case where all of the maps in a

[pfx] Re: Forward mails if user unknown in local recipient table

I would like to know if i can configure postfix to forward mails if user not found in local recipient table. That is possible (with static: mapping) but not a good idea. May i know why it's not a good idea? Users are split between LDAP in my server and a remote server for example.com. So

Thanks to Bill and Benny for the pointer to https://www.postfix.org/DEBUG_README.html#mail. Using tcpdump I figured out that a monitoring task using OpenSsl (with hardcoded mail.example.org) was reusing the same ip (via NAT). You´d call it gremlins  Joachim -Ursprüngliche Nachricht-

[pfx] postfix alternating between mail.example.com and real hostname?

I haven´t seen this before, but at present my mail server is kind of alternating between mail.example.com and the real hostname (or someone is spoofing my IP-address which I doubt). All configuration files I checked indicate the correct setting and postconf myhostname returns the correct name.
