Contact Comcast. We had a similar issue and it turned that Comcast had blocked that one domain on their end because Comcast thought the mail they were sending was spam - they are an Insurance company sending quotes to agents - everyone who is getting a quote has asked for it because they only quote to agents not consumers direct. Comcast removed the block and we have not had a problem since. Comcast indicated they had not received any complaints but their filters had identified spam coming from that domain. You can imagine the words insurance and quote were probably triggering something. The generic message in the log looked like it was a PTR problem but it was not.

Are you guys adding a ptr with the client domain for every domain you host? Again, I've never had a complaint on this so I'm thinking it's not necessary.
