BTW, the most recent version of Mailman is 2.1.9, which has a number
of new features and some fixes for certain security holes. I'd
strongly encourage you to upgrade.

Go to the web admin page for your list, then go to the sub-page for
"Mail<->News gateways". Is the news server hostname filled in? Is
the newsgroup name filled in? Is the moderation policy set
correctly? Do you have the radio buttons set correctly for passing
traffic both ways?
In your mm_cfg.py file, do you have the correct definitions for the
username and password you need to use when logging into the news
server to retrieve and post articles?

Correct. Mailman does not attempt to obscure addresses when posting
mail messages to a newsgroup.

Not so far as I know, but it shouldn't be hard to add. However, one
problem you'll have is that many news servers will reject your
articles, if you use an address obfuscation scheme that they don't
So, your choices are to not do any obfuscation at all for news
articles (which is what Mailman does today), or see if there is some
common format of obfuscation that virtually all news servers are
known to support.
Of course, if they support it then the spammers probably already know
about it as well, and anything you can do they are likely to be able

I think what happens is that the subject header will get treated as a
normal subject, and may have additional things tacked onto the front
of the subject line, whereas normally Mailman would have recognized
the "Re:" portion and potentially tacked those things on between the
"Re:" string(s) and the rest of the subject.
But one of the core Mailman developers would be more likely to know
the answer to that question, and they're also on this list.
Hopefully they'll be able to respond to you within a few days.
