Is it possible to have incoming mail to my domain on port 25 go to one IP (mailserver) and have Authenticated sessions on port 25 go to a different IP?
While traveling, not all of the intranets I'm connected to allow port 465 outbound for SMTP-SSL. But most will allow port 25 out. I'd like to have all incoming mail to my domain sent to one IP on my mailserver but have any mail sent by an authenticated session (me sending mail remotely) sent to a different IP on my mailserver. To avoid relay issues. I only want to relay mail from authenticated sessions. My mail server can be set to treat mail from certain IPs as "Trusted" and relay them.
Any ideas?
