I am having issues with trying to trace email being sent into my system.
I have used the zmmsgtrace command and am able to successfully lookup email being sent in, but when I try to look for an alias as the recipient it is failing.
The test I did was to send email to the email@example.com from a different email address on an exchange server and also from GMail.
The exchange email did not make it, but the GMail did. Any ideas why this may be occuring? If I do not send to the alias, but send to the real account from exchange I receive email.
