Allow posting from addresses with modifiers?
Folks:
Anyone know if it's possible to configure MM 2.1 to allow posting with an email address that has a modifier?
For example ... if someone is subscribed as "john+lists@example.com", but their email comes from "john@example.com", allow that address to post?
I've had some people ask me about this ability because they want to use the modifier address to help them filter messages.
Thanks!

You can't configure Mailman to just do it without making code changes, but there are possibilities:

To place the burden on john, he can subscribe both addresses and set john@example.com to nomail.
To place the burden on you, assuming you have access to Mailman's command line tools, you could periodically (via cron) run a script to list the members, find those with '+' in the local part and add the address without the +... in the local part to the list's accept_these_nonmembers. There is a script at <https://www.msapiro.net/scripts/non_members> (mirrored at <https://fog.ccsf.edu/~msapiro/scripts/non_members>) that can do the adding to accept_these_nonmembers.

OK, thanks.
I might play around with that at some point in the future.

This is what I have done for many mailing lists. — I subscribe with one private address for email filtering and reply from another public email address.
I suggest that the member also pick one and toggle the option to hide (the non-public subscribed address) from other subscribers.

I don't see any obvious security related down sides to this. It does open the mailing list up to messages (spam) from some additional addresses. But I can't think of any cases where user@domain.tld would be different than user+detail@domain.tld. I guess maybe some sort of ticketing system /might/ do something like that. But I bet that the intersection between such configurations and Mailman configured as Mark is describing to be quite small.
