The interesting thing (at least to me) is that prior to my mail bouncing from Ollivier, I have *never* had such an incident, not even without using a 'smarterhost'. RoadRunner is as antispam as any ISP can be expected to be, and they run open relay tests on a regular basis to prevent the kind of abuses that have been mentioned earlier in this thread... I really cannot imagine why anyone would block my mail based solely on the 'no cable modems here' principle... Wow. On Wed, Dec 20, 2000 at 12:33:06AM -0800, Crist J.

You might want to consider a mail to the > 'postmaster's at both ISPs. They should really work this out. It looks I don't really see anything unusual about this... It's pretty common for mail.whatever.domain to be an alias, no? I think every ISP I have ever used had a mail gateway called mail*.whatever.domain that resolved to some other host than 'mail'.
