Re: [cpx] CPX Quirk -- Tom, Dick & Harry

Brian:

It appears that when an email is sent to a subdomain it won't forward.
At least not on my VPS3. To duplicate more easily, I have removed the
unnecessary complexity of multiple aliases from my earlier scenario.

To prove that it works when sent to a "domain":
. I created a user named "aaa" and put him in domain.com
. I sent an email to him at aaa@xxxxxxxxxx
. As expected, it arrived just fine
. Then "aaa" changed his "mail forward" to zzz@xxxxxxxxxxxxxxxxx
. I sent a 2nd email to him, the email was forwarded just fine
. Everything worked as expected.

Important:
. For this to work I added an MX record for subdomain.domain.com
. And I left the MX record for domain.com there

To prove that it "does not" work when sent to a "subdomain":
. I created a user named "bbb" and put him in subdomain.domain.com
. I sent an email to him at bbb@xxxxxxxxxxxxxxxxxxxx
. As expected, it arrived just fine
. Then "bbb" changed his "mail forward" to zzz@xxxxxxxxxxxxxxxxx
. I sent a 2nd email to him, but it was "not" forwarded
. It was delivered to the "bbb" local folder instead.
. This was not as expected.

Notes:
. It works if I add "bbb: zzz@xxxxxxxxxxxxxxxxx" to the aliases file
. But end users are not able to hand edit that file
. None of the above scenarios made any updates to the "aliases" file
. They must be using something I haven't figured out, like procmail

Warm regards,
Chuck Langenberg
