Mail list address problem (FW: Returned mail: see transcript for details)

[Suhaib Siddiqi]

Sometimes I get mails fromlist with a Reply to filed as
xfree@xfree.cygwin.com, when I hit a Reply button and send a reply the
message bounces back with User User Unkown, error.  I wonder then how the
message was posted at first time?
