Comments: I am not familiar with the Mailman code. I am not sure if there is a simple fix. At really first glace Utils.py has some probably incorrect code in the ParseEmail function. I am not sure if this is the cause, and if so, if it has any side-effects by changing it. I know Mailman internally stores the user part as lower case, but for mail delivery purposes it should retain the case. The function (in 2.1.6b4) I am guessing should probably look more like this: def ParseEmail(email): user = None domain = None at_sign = email.find('@') if at_sign < 1: return email, None user = email[:at_sign] rest = email[at_sign+1:].lower() domain = rest.split('.') return user, domain ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100103&aid=1155029&group_id=103
