Dccm, dccproc, and dccifd whitelisting is based on checksums.  There
are no regular expresions.  If you can find a checksum that covers
the sender, then you're set.  Otherwise you must do something outside
the DCC client code. 

Have you looked at white-listing by "mail_host" value?
For examples, see the sample white-list in homedir/whitecommon.

Yes, provided you also use `misc/hackmc -O` or an equivalent to adjust
