They key difference between the MSA and the MTA is that the MSA is targeted at outgoing mail and the MTA is targeted at incoming mail. So clearly you are going to want anti-virus/spam etc. filters on the MTA to deal with the incoming menace. Whether you want such filters on the outgoing traffic is a matter of preference, but splitting the functionality between MTA and MSA gives you the option of not applying the same filters to outgoing traffic if you don't feel the need to have them. > > fetchmail can deliver the fetched mail differently than just to a > > running MTA on port 25. > > Are you talking about the -S option for fetchmail? > (Keyword: smtp[host]) Specify a hunt list of hosts to forward mail to (one or more > hostnames, comma-separated).

You can use an MDA (Mail Delivery Agent) like procmail to handle delivery instead: poll mail.myisp.net with uidl protocol pop3 user username pass "password" is me@xxxxxxxxx here mda "/usr/bin/procmail -d %T -f %F" fetchall nokeep ; Paul. -- Paul Howarth <paul@xxxxxxxxxxxx>
