Mimedefang usually puts forth some very specific error messages, and that doesn't look like one to me. Is it possible you may have another milter running that does some form of call back like VRFY or EXPN or something of that nature to validate a sender. The fact the address is coming from navy.mil tells me that's likely what's happening because standard government configurations call for disabling these features to the MTA. With them disabled, a test of that nature would fail. Do you get any other similar rejects from other government or military addresses?

It's getting rejected with the "Domain unable to resolve" error, but look at the log entry: > > Jan 13 16:57:35 smtp-in1 sendmail[29029]: [ID 801593 mail.info] > j0DMutQN029029: Milter: to=<[EMAIL PROTECTED]>, reject=451 4.1.8 Domain of sender address [EMAIL PROTECTED] does not resolve > > It seems to say that the milter is rejecting the email, because usually it will say something like "ruleset=check_rcpt" but here it says Milter. I don't have the error string in my mimedefang-filter file. Is MD rejecting this email?
