Hi everyone,
I have an external MTA configured with Postfix that delivers email to an internal IMAP/LMTP Dovecot server configured to bind an LDAP to check if users exist.
If the user does not exist, my MX sends a non delivery notification, and into the e-mail there's the local IP address of the Dovecot server.
I can't find a way to remove or hide that IP, here is an example of line that contains the IP (with X) that I would like to hide/remove:
*"The mail system<user@domain>: host hostname.domain.com <http://hostname.domain.com>[XXX.XXX.XXX.XXX] said: 550"*
Thanks in advance!
Cheers
