Courier is *VERY* particular about the sending email server domain name matching the one it gets when it checks of the machine - if it doesn't match, it bounces. My logs are running with some degree of scrutiny, and I can see several emails on "re-send" from mail servers that don't match the name in the header - while most are spammers, sometimes some aren't, including occasionally larger legitimate ISPs. -- Mark L.
