Possibly OT: VERP to plussed addresses
I have noticed that Mailman seems to be capable to correctly parse bounces that come from a plussed address. Example: I'm subscribed to this list with
cite+mailman-users@example.net
so the sender address looks like this:
mailman-users-bounces+cite+mailman-users=example.net@python.org
While it's very nice that this is working - _why_ does it work? Does Mailman simply start at the leftmost "+"?
Oh, and BTW: Happy "1st of a month", python.org listmasters! Enjoy your bounces ;-)

The short answer is yes. For the long answer, see the definitions of VERP_FORMAT and VERP_REGEXP in Defaults.py.

And a Happy Mailman Day to you too ;).

Sweet, does this mean I get the day off work?

For a read-only announcement list, I'm looking for a way to set up "one-click subscription" where a user enters an email in a form on a web page and gets subscribed right away, with no confirmation needed.
Thanks in advance for clues on setting this up with MM, Apache and postfix.
Apologies in advance if this has been asked before. I didn't see anything specific in the FAQ or in a quick check of the archives.

Note that you're going to open yorself up to the problem of people being gratuitously subscribed to your list. That's why we have double opt-in.
There's a disturbing trend these days of people reporting mailing lists as spam to their providers instead of unsubscribing. This can get you blacklisted. It happens enough with lists that people actually voluntarily subscribed to, it's going to be a lot worse if you get people being randomly subscribed without their consent.

This is not a good idea. It allows anyone to subscribe anyone else to your list without the subscribed person's knowledge or consent. Do you really want to do this?
If you do, there are two ways.
You can set
ALLOW_OPEN_SUBSCRIBE = Yes
in mm_cfg.py and then set the list's Privacy options... -> Subscription rules -> subscribe_policy to None, and create your subscribe form per the FAQ at <http://wiki.list.org/x/hIA9>.
Or, you can create a web page that either invokes curl or wget or posts it's own data to the admin CGI as outlined in posts linked from the FAQ at <http://wiki.list.org/x/uIA9>.
However, if what you want is for people to be able to subscribe without further interaction on their part, you might consider just setting subscribe_policy to Approve and having subscriptions approved by an admin or moderator. This isn't much better, but at least it allows the admin to detect a suspicious pattern.

OK, thanks. Thinking about this some more, it does seem like an excellent way to subscribe users who never asked to hear from us. I'll recommend to our team that we at least get confirmation before proceeding.

Also, you should note that in some places anti-spam laws make it illegal to operate mailing lists that only require one-click subscription. My slightly fuzzy memory says the laws surrounding this were most strict in Germany, but I wouldn't be surprised if other countries require confirmation before someone can be put on a mailing list.

Please let me know the domain(s) these lists will be hosted on so I can add them to my local blacklist.
