Recently went sub-domains. In order to keep backward compatibility, we've
setup forwards for the "important" address.
Example, /etc/aliases:
support@???: support@???
Part of the sub-domain move was so I could control the MX hosts for
subdomain.tld.com and not have to depend on the main mail hub for spam
protection.
The problem is now spammers send mail to support@???, they get forwarded
to MX host for subdomain.tld.com, a callout happens, and from what I can see
in the logs, the callout goes to tld.com, which passes.
How can I make subdomain.tld.com do a callout on the sender for the
originating sender, not the forward of tld.com?
