Known problem with old Python code. Upgrade to Mailman 2.0.1 and all will be well again. (Mailman started supporting Python 2.0 sometime around 2.0beta3 if I remember right.)

We are currently using Python version 1.5.1 and Mailman version 1.0. We wish to move to Mailman version 2.0. In preparation for this I installed Python version 2.0. A bad thing was noticed ;-) mail was accepted into mailman but not distributed out. Looking at the smtp-failures log file I see messages of the following type

28 10:07:04 2001 TrySMTPDelivery: To ['A.D.Person@shu.ac.uk', 'J.Someone@shu.ac.uk']: Jan 29 10:09:26 2001 TrySMTPDelivery: exceptions.TypeError / connect requires exactly 1 argument; 2 given (dequeued)

Is/was this a known problem and if so can I expect the same thing using version 1.5.2 of Python (the minimum for installing version 2 of mailman)?

Incidentally [to add to the list of MTA mailman is known to work with] I have installed it with Nexor's PP or Mailer software and will write up the installation quirks if anyone is interest.
