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 at domain>: host hostname.domain.com <http://hostname.domain.com>[XXX.XXX.XXX.XXX] said: 550"* Thanks in advance!

Then you don't care because the IP of the postfix server is almost certainly your MX server.> 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 at domain>: host hostname.domain.com[XXX.XXX.XXX.XXX] said: 550"> Thanks in advance!> Cheers> -- > Claudio
