[pptp-server] administrivia: change to postfix MTA.

[Christopher Schulte]

FYI:

I've migrated this list server from Sendmail 8.12.0Beta12 to 
Postfix-20010228-pl03.  This has been done mainly for performance 
reasons.  Sendmail has a reputation of being very slow and inefficient for 
the large mail volume that a mailing list server can sometimes need to process.

This should improve the speed and reliability of messages posted.  It might 
also make my life easier, as I won't have to clear backed up messages 
nearly as often. :-)
