I doubt that making calls via mimedefang is just a 'couple more' cpu
instructions over internal calls within postfix.
But yes, it would be nice for other non-daemonized stuff.
So just chalk sendmail down one notch for lack of multiplexed
mysql/postgresql support versus postfix will you? mimedefang cannot
completely rectify that for sendmail.
