one other thing that I saw with expect...if you open a telnet connection
to the amavis port, it uses up 1 of the 4 possible threads. If it
doesn't disconnect, it will use up another one at loop time. I've seen
it used with ftp and when things went wrong, there were gobs of ftp
connections to the server...sort of like a self-generated DOS ;-)
