What do you mean by "reject"?

Here's what I do :
    1)  require verify = header_syntax


        This kills quite a bit of stuff at SMTP time.  For example
            To: <Mainly Millionaires>
        (yeah, I'm a millionaire, can you believe it?)


    2)  A hodge-podge of ACL rejections.  I reject a variety of
        automatic virus warning messages and "read receipts" or
        anything Content-Type: application/ms-tnef that comes from the
        outhouse.  These used to 'fail' in my system filter, but I've
        moved a bunch of these up to the ACL level.


    3)  http://marc.merlins.org/linux/exim/sa.html


        I permanently reject stuff over 10.0 and accept everything
        else.  I don't scan locally generated mail, already-scanned
        mail, and certain From: addresses.  I save all rejected
        messages in a psuedo-maildir folder.  (the directory it saves
        to happens to work like a maildir folder because I made it
        that way)


I think #3 is the real key, but #1 is a good sanity check in the first
place and #2 is just plain doable with no ill effects. I see "new"
messages in the reject folder when they arrive, and I check my
rejectlog periodically. When I first went live with sa-exim I saw
several messages a day hitting the junk pile. Now I see one or two.
The advantage is I reject the mail at SMTP time rather than creating a
bounce later. If you don't reject the mail, then the address is
"verified" and not likely to be removed from the spam lists.

That's an interesting trick. I only have one address and I use it for
everything. (except for exim-users, I still have that pointed to my
school address (which forwards to my main address) in case my server
becomes unusable again for some reason)

HTH,
