Let me re-state the point: If the recipient's domain name is in the left hand side of the sender's address (to the left of the @) then it's probably from a list server. You could also look for the word "bounce" in the sender address.
I don't see how sending through an ISP SMTP server is relevant. If it's from a mailing list AND from a DUL or listed in SpamCop or MailPolice, then it's probably junk.

With port 25 blocking becoming more common to force ISP subscribers to route all email out through the ISP SMTP server the sender address is likely to show the ISP email address while the From: line will show whatever email address they normally use depending on the SMTP Auth setup.
