Hi all,
do anyone know how to alter the mail-from of a postfix mail server?
Example, I have a postfix mail server which sends mail for the domain example.org.
When a linux user, whose account is user.example.org (mapped in postfix/virtual to
[email protected]), try to send an email, its mail from is
[email protected].
HELO hostname: server.hostname.org
Source IP: one ip here
mail-from:
[email protected]
Problems:
user.example.org instead of just user.
server.hostname.org instead of just example.org.
Desired mail-from:
[email protected].
This is causing me problems with SPF records for example (example.org differs from server.hostname.org)... any idea of what can be the problem?
Thanks in advance,
Simon.
