[Mailman-Users] Regexp for blocking addresses

[Matthew Saltzman]

I am trying to block variants of ceertain gmail addresses but I'm having
trouble concocting the right rexexp to accomplish the task.

Gmail addresses can contain embedded periods and can be followed by a
'+' and an arbitrary suffix. So all the following are the same address:
      * joebloe at gmail.com
      * joe.blow at gmail.com
      * j.o.e.blow at gmail.com
      * joe.blow+abcd at gmail.com

And so on. I've tried various regexps, but none have worked so far.

     1. Could someone show me the right syntax to catch all embedded
        dots in the part before the '+'?
     2. Is there a way to script removing all my experimentation from
        the ban lists on multiple mailing lists?  Things are looking
        pretty cluttered by now on the privacy admin pages.

Thanks very much in advance.
