1)Save the patch to a file.

2)Edit the file with an editor that won't change indentation or wrap or
fill lines, i.e. a text editor, not a word processor, and change
problem_list in the line

+    if listname = 'problem_list':

to the all lower case name of the list. If you wanted to apply it to a
few, but not all lists, you could change the line to something like

+    if listname in ('problem_list', 'list2', 'list3'):

Note that the quotes around the literal list names are important, but
there are no quotes around the variable listname.

3) Give the command

cp /path/to/mailman/Mailman/Cgi/subscribe.py

(all on one line)

4) Give the command

patch /path/to/mailman/Cgi/Mailman/subscribe.py < /path/to/edited/patch

(all on one line)

5) Go to a URL like <http://your.server/Mailman/subscribe/problem_list>

Note you don't need to restart Mailman first as this patch only affects
web accesses which are always new CGI processes.

The possible results are:

1) A page that says


Web subscribe not allowed /problem_list/

This says all is good.

2) A page that says

problem_list Subscription results

You must supply a valid email address.

This says the patch wasn't applied or for some other reason (maybe
problem_list not changed or misspelled) isn't working.

3) a page that says

We hit a bug.

This says there is something broken in the patched module. You can leave
it broken which will disable all subscribes or maybe only problem_list
subscribes depending on the exact error, or you can copy the
subscribe.py.bak file from step 3) back over subscribe.py.

In any case, Mailman's error log will have an exception and traceback
from what went wrong.
