List Owners: Solve Address Migration Problems by Creating a White List

listmaster@lists.uoregon.edu

As many of you may know, Darkwing users can now choose to use username@uoregon.edu instead of username@darkwing.uoregon.edu (see http://cc.uoregon.edu/cnews/fall2002/dw_address.html)

While this is a nice change for email users, it may cause a few problems for list owners.

Majordomo expects posts for closed lists to come from the user's SUBSCRIBED email address. In most cases this will still be darkwing.uoregon.edu, so posts from username@uoregon.edu will bounce to the list owner if the actual subscription address is from Darkwing. Conversely, users who have changed to username@uoregon.edu and have subscribed from that address may still send messages that bounce if they use webmail (email.uoregon.edu) which sends mail as username@darkwing.uoregon.edu

How can you fix this without subscribing to both addresses (which will cause the user to get two copies of each message)? Create a white list!

A white list is a secondary posting list that allows you to maintain a "hidden" list of users' addresses that can post to the list but don't get copies of list messages. For details, see http://darkwing.uoregon.edu/~llynch/majordomo/secondary.html


Warning: The only "gotcha" here is that in order to make this work you will have to turn off welcome messages for new subscribers.
