I have a corporate customer who is in the process of migrating all of their users and services from one domain to another (lets say reallyreallyreallylongandhardolddomain.com to newdomain.com). Because they are quite large, and not centralized they estimate that it will be about a month before they are able to get out to all the remote sites to convert the user mail settings to the new domain. They use mailman for much internal mailing between various groups of their users.
At this point the mail server is configured to respond to both domains, and treat them as the same. Mailman itself is configured to use the new domain both on the web side, and all the lists have been changed to use that as their preferred domain. However the problem arises with the list subscribers themselves. We can't simply export the membership for the lists and change everyone to the new domain because everyone won't be sending with the new addresses at once. In the worst case scenario we could export the list make the changes and reimport with nomail set so that everyone has a duplicate membership, and then remove the old domain accounts once the conversion is complete. I'd prefer to save this as a last resort at this point as it is kind of messy. What I would like to do is do a one-shot conversion of all the users to the new domain name and then internally to mailman, when the message is first submitted into the mailman process simply have a regex replacement of the sender's domain name so even though the message might actually be coming from [EMAIL PROTECTED] mailman would read that in, do a quick replace in its mind and for the rest of the process treat the message as if it had come from [EMAIL PROTECTED] I am assuming that this should pretty much be a 'one-liner' code modification to mailman. Pardon my Perl (I'm not a native Pythoner so that doesn't help matters :-) but the equivalent of "sender =~ s/olddomain/newdomain/" immediately after mailman parses 'sender' from the incoming message. I don't really grok how the message flows through the internals of Mailman... so the couple of places I've tried putting the 'one-liner' don't seem to have any effect. I'm assuming that this should be done literally as soon as possible after Mailman has received the message from the MTA to ensure that the substitution is used in all possible processes? I'm hoping someone on the list may be able to tell me if this a) is really a one-liner and b) roughly where to look at inserting the 'one-liner' in order to acchieve the required result. Thanks for your help!
