The `To' header on the email I received was interesting. To: nmh-announce: ;, ""@ruis.pair.com, nmh-workers@nongnu.orgSigh. I wonder which piece of software did that?
Whatever did it, it is apparently a widespread method of re-writing of the line.. To: nmh-announce: ;;@gmail-imap.l.google.com, nmh-workers@nongnu.org Makes me think that a lot of mailservers are canonalizing by adding '@my.address' to anything that doesn't have an @ on it already. So they deal OK with the nmh-announce: part, and then the ; standing by itself gets treated as 'non-alphabetic local mailbox name' and gets hit with the local server's fqdn.... Ken - do you have handy the To: line *as it left your local machine*? I suspect the flaky here is very dependent on exact placement of blanks and other special chars... Though I have to admit I don't have enough caffeine in hand to delve into the parse tables as given in the RFCs at the moment...
