What happens is all incoming (via SMTP) messages are frozen and
then handled by a process external to exim, to decide if it's spam
or not. The very last phase (done outside of exim) involves adding
a special header to each outgoing message and rewriting the
addresses.
If you're wondering why I don't let exim handle this, there's two
reasons. First, the added header differs from recipient to
recipient and isn't added for all recipients. The second, and this
is the killer, is that this header is added *only* if the address
is rewritten -- if I send mail to A, no header; if I send mail to
B which is rewritten to A, I add the header.
The reason I need to send the thing by SMTP, BTW, is that I don't
do the special processing for locally generated mail. However, if
I send mail to one of those addresses (B, above), I need them
processed. So, I cheat: I send them via SMTP and then they aren't
locally generated anymore. :-)
