Mailman (2, I assume) will set the MAIL FROM to its host, as defined by DEFAULT_EMAIL_HOST in mm_cfg.py, or to the virtual host if you have those defined. (Not sure offhand where the latter is defined.) > The handling of the message was: > > Return-Path: <gpa-boun...@lists.ripplingwater.us> > Received: from pdx1-mailman01.dreamhost.com If you have a physical host, most likely "lists.ripplingwater.us" is the MAIL FROM, I think, but if you have a virtual host managed by a third party (Dreamhost?), it could be anything (pdx1-mailman01.dreamhost.com is a possibility). > and in the maze of headers there's > > Action: failed > Status: 5.1.0 > Remote-MTA: dns; mx1.comcast.net > Diagnostic-Code: smtp; 550 5.1.0 Invalid sender domain This is saying that mx1.comcast.net refused the mail as soon as it saw MAIL FROM. That means that your ISP (Dreamhost?) is responsible for the email you received, not Comcast. I'm in Japan, so that might be the problem, but this does not look good: % host lists.ripplingwater.us ;; connection timed out; no servers could be reached % host ripplingwater.us Host ripplingwater.us not found: 2(SERVFAIL) % host lists.ripplingwater.us lists.ripplingwater.us has address 64.90.62.204 Host lists.ripplingwater.us not found: 2(SERVFAIL) Host lists.ripplingwater.us not found: 2(SERVFAIL) % host -t MX lists.ripplingwater.us Host lists.ripplingwater.us not found: 2(SERVFAIL) % % host -t MX lists.ripplingwater.us lists.ripplingwater.us has no MX record host -t NS lists.ripplingwater.us Host lists.ripplingwater.us not found: 2(SERVFAIL) % host -t NS lists.ripplingwater.us lists.ripplingwater.us has no NS record Your nameservers appear to be misconfigured (no MX, no NS?), and the multiple failures suggest they're very busy (perhaps under DoS attack?) Hope this helps.
