Hello!
First of all, I apologize if my question is somewhat flawed formally or
semantically (it may be excessively stupid without me realizing, for
example), I have searched for the answer myself without success, and
only after failing, I am submitting my problem here as a last resort.
My question is this - transport table in Postfix allows matching by
address (user@domain), by domain itself, or the * wildcard can be used,
but what if I want to match mail from every domain that have a specific
server (ip) in their MX record?
The purpose would be this - due to the trouble with blacklisting, I want
a special, throttled transport for any domain that uses Microsoft
servers to receive mail for them - I know the IPs of the Microsoft
servers, but any number of domains, anytime (even in future), may start
or stop using these servers, and I want my mailserver to use that
special slow transport for them for all outgoing mail.
I hope I expressed my purpose clearly enough, and I thank in advance for
any advice given on the subject.
