"#" in mail address confuses mailman

[Effbot]

someone recently managed to subscribe himself to
the python.org image-sig mailing list, using an add-
ress looking a bit like this one:

    prefix#<email address hidden>

unfortunately, the web interface doesn't escape the
"#" character, so the web pages for this user cannot
be accessed:

    http://mail.python.org/mailman/options/image-
sig/prefix#user--at--some.com

(the browser strips off the "#" and everything after
it before sending the URL to mailman...).

I'm not sure what version python.org is running,
but I suspect that the Barry person might be able
to figure that out.

cheers /F

Tried to replicate the bug on Mailman 3, was able to subscribe an e-mail id with abcd#<email address hidden>.
The webpages related to the user were found to be accessible.

This is a Mailman 2.1 bug, not a Mailman 3 or Postorius bug. While it is the case coincidently that this bug was fixed in Mailman 2.1.10, that fix did not specifically target this bug and its status was not updated. It happens that 'Fix Released' is the correct status for this bug, but that is just a coincidence.

I have done a good amount of work regarding this, the work summary is here : https://bugs.launchpad.net/mailman.client/+bug/1429366 .
