[Bug 614550] [NEW] Invalid warning do not list domain domain.com in BOTH mydestination and virtual_mailbox_domains

[Lefteris]

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: sender at domain2.com> <To:
sender at domain2.com> but using the outside unauthorized mail server
send.domain1.com
