Seconded. I send through them all mail to sites that block me via an RBL,
and don't have problems, even though the From: address is my own. I also
do not use a Comcast address on this (or any other) mail. Their servers
accept all mail that comes from any node within their network; all they
monitor for, AIUI, is volume (to identify customers that are spammers).

Your folks should be able to change their SMTP setting within Outbreak to
"smtp.comcast.net", and never notice any difference ... other than that
their mail now goes out successfully, of course. ;)
