My company - fred.com - sends internal mail to an external MS Office email exchange, using MailEnableAdmin on Windows, primarily for server alert mail.
The plan is to move away from MailEnableAdmin on Windows to a CentOS server.
I have successfully configured a mail relay with postfix to send internal mail to the MS Office exchange to multiple addressees.
However, we also have a client/customer that we host servers for - mary.com - and they use our existing Windows Relay to redirect messages coming into "email@example.com" to "firstname.lastname@example.org", and redirect emails coming into "email@example.com" to firstname.lastname@example.org. I have tried to 'redirect' both addresses to "email@example.com", so I'm the only one that sees them, but I can't seem to get the redirection to work.
I have tried to set up 'sender_canonical_maps', see below, but the firstname.lastname@example.org (or email@example.com) does not get redirected to firstname.lastname@example.org, it ends up being delivered to the MailEnableAdmin server. What have I missed in the configuration?
