Could you submit a patch to the bug tracker (bugs.python.org)? 2007/10/20, Derek Shockey <[EMAIL PROTECTED]>: > smtpd.SMTPChannel contains a bug such that when connected to an SMTPServer > (or any subclass thereof), issuing a MAIL command with no argument closes > the socket and gives this error on the server: > > error: uncaptured python exception, closing channel < smtpd.SMTPChannel > connected 127.0.0.1:58587 at 0x847d8> (<type > 'exceptions.TypeError'>:'NoneType' object is unsubscriptable > [/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/asyncore.py|read|68] > [/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/asyncore.py|handle_read_event|390] > [/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/asynchat.py|handle_read|137] > [/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/smtpd.py|found_terminator|158] > [/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/smtpd.py|smtp_MAIL|224] > [/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/smtpd.py|__getaddr|212]) > > The desired result is of course is to respond with a 501 Syntax error.
