Here's something odd: On several IRIS's that were working just fine, suddenly within the past week we get complaints from users that they can't send mail. The diagnostic: "cliff@research.nec.com: rewrite: expansion too long" and /usr/lib/sendmail -bt gives @research.nec.com: @research.nec.com: @research.nec.com:... [ad infinitum]... cliff@research.nec.com We haven't touched sendmail, or the name server, or YP, or anything else as far as we know. Why does this suddenly appear out of nowhere? And how does one permanently fix it? --cliff@research.nec.com OR, if the mailer bounces it back (!) --millercb@phoenix.princeton.edu
