1. we delay checks
2. I've seen code that adds custom headers for SA to score them,
by rewriting INPUTMSG in its entirety. I don't recall if it
also updated HEADERS, or if it wrote HEADERS first and then
made a call to recreate INPUTMSG. Maybe not the most efficient
thing to do, but given the other processing that goes on in
spam detectin, probably not a big additional impact either.
3. On our system, I believe that /etc/aliases might be a hash
database, and therefore it seems that it might be pretty
easy to lookup recipients in the alias hash directly?
Though clearly invoking sendmail to do this is safer,
and the result could be cached internally and the cache
flushed if /etc/aliases time stamp is updated.
