One more thing: just caught this today, with the current stable release:

in logs/smtp-failure: smtp-failure:Aug 28 17:28:31 2005 (1433) All recipients refused: {'randiminetor@ highfallsfilmfe...': (501, 'Bad address syntax')}, msgid: <1b89848bfc55965b74421 44bb122ad4d@minetor.com> smtp-failure:Aug 28 17:29:18 2005 (1433) delivery to randiminetor@highfallsfilmf e... failed with code 501: Bad address syntax

I assume it is abbreviating the email address, because I am certain the sender is using the proper email address. What might be causing the error?
