No, fetchmail can also work without a local MTA.
It can pass fetched emails to a local programs or scripts, like:

# cat /tmp/deliver.sh

cat >> /tmp/text

# fetchmail -u user -m /tmp/deliver.sh mail.server
Enter password for user at mail.server:
1 message for user at mail.server.
reading message user at mail.server:1 of 1 (1631 header octets). (5 body 
octets) flushed

And we have a mail written to /tmp/text.

But I don't want or need any MTA here ;)

So I guess it's just a matter of simple scripting: fetching correct 
email using fetchmail, and passing it to mail/mailman program in a 
correct way. Anyone has it documented?
