Public bug reported:
Binary package hint: postfix
There should be no warning at all since mx.domain2.com is not listed
nowhere in mydestination in main.cf. The invalid warning occurs every
time an email is sent trying to impersonate the destination domain but
originating from an outside unauthorized domain, as a lot of spam is
trying to do these days.
For example, sending an email <From: sen...@domain2.com> <To:
sen...@domain2.com> but using the outside unauthorized mail server
send.domain1.com
