Am I misunderstanidng what you're saying?
My domain is www.espphotography.com . But my mail is relayed through
my ISP's mail server - smtp.dslextreme.com . So my mail should be rejected?

I am new to postfix/SpamAssassin and thinking for a way to block the
email address which does not come from that domain. For example, if
someone with a @xxx.com email sends to a list it must come from a
server in the xxx.com domain else it should be rejected. Is it
possible to do this? As there is every possibility that spammers can
also send with real user's id and I am planning to have a check that
would be able to compare the From: and the Message-Id domains to
check for spoofed messages coming in from an open relay. Its just an
idea to eliminate every possible attack. As i don't have much
experience with postfix, just installed/configured a couple of days
ago any suggestions in this regard will be highly helpful for me. I
have also read some whre about Sender Score Certified support in
SpamAssassin. But not sure how this works? Will it check the
senders from address and compare it with the domain?
