Don't forget read/delivery receipts have a null ("<>") mail from.

Hi,
I have a scenario where i have a submission port/ip, where users can
relay through and doesnt do any RBL checks as such. However, what i
have noticed is that if the user authenticates, he can then send a
message with any from address.
Is there a way to limit them such that at the very least the domain
name used to authenticate is the same domain used for the from. I dont
want to limit it to the exact same user, as many times offices use a
mailer daemon/postmaster or something and use it as a relay for their
office, which means 1 authentication for that whole office. Or perhaps
a file that maps which domain is allowed to authenticate and send
relays for
like
domain1.com:shupp.org
domain2.com:shupp.org
domain3.com:blah.com
That means if your from address is domain1.com either domain1.com used
for authentication or an account on shupp.org used for
authentication will be accepted as relay for that address
What do you guys think?
