Using 1.78+ Pro, you can use the following in a custom filter

MAILFROM   END   ENDSWITH   @comcast.net
REVDNS         5         ENDSWITH   client.comcast.net

You could probably throw a list of END statements for various domains in there as long as you know the naming convention for the REVDNS entries and can isolate them to their residential IP space (which can't be done for all domains). Also note that this will often double hit with SPAMDOMAINS, and I do see some false positives on SPAMDOMAINS when boneheads buy themselves bulk-mail software to run on their residential-class service and use accounts on places like yahoo.com as the MAILFROM. I think this might be worth a few more points though.

Is there a way to add weight when
- received from client.comcast.net BUT sender is not "@comcast.net"


Here are example headers:
