Hello everyone, I have been running postfix for two mail domains (say,
domain1.net and domain2.net) for a while and everything works fine.
However, in my main.cf configuration file I have set myhostname =
mail.domain1.net and thus, every mail received from my postfix SMTP
contains a header line of the form:
Received: from mail.domain1.net (.... [xxx.xxx.xxx.xxx]) by ...
This annoys me as I prefer not to mix domain1 and domain2. I thus
decided to set up two new transports in master.cf and use
sender_dependent_relayhost_maps.
I add the two following lines to master.cf:
domain1 unix - - n - - smtp
-o smtp_helo_name=mail.domain1.net
domain2 unix - - n - - smtp
-o smtp_helo_name=mail.domain2.net
and the following line to main.cf:
sender_dependent_relayhost_maps = regexp:/etc/postfix/relay_reg
Then relay_reg contains:
/@domain1\.net$/ domain1:
/@domain2\.net$/ domain2:
From what I read everywhere, this should work after a run of postmap
relay_reg and postfix reload but it does not...
When I try sending an email I then get an error mail back with the message:
<...>: Host or domain name not found. Name service error for
name=domain1 type=A: Host not found
It seems that instead of using the transport defined in master.cf,
postfix tries to relay the mail to a host called domain1... I have no
idea why so any help is welcome!
I run postfix 2.6.5 on a gentoo server, here is what postconf -n returns:
