[Mailman-Users] Unable to remove invalid e-mail address

[Tim H.]

Somehow an e-mail address with the below form was subscribed to one of 
my lists:

"user at domain.tld /"

The e-mail address does not show up in the web interface, nor does it 
show in "list_members", "find_members", or "list_members -i".  I also 
tried using withlist.  Essentially, I tried everything on this page:

http://wiki.list.org/pages/viewpage.action?pageId=4030544

But, the e-mail address persists.  Does anyone know of another method 
for removing this address?  I've been trying to use dumpdb to dump the 
config.pck to a text file, and manually edit them out.  However, the 
config_list command does not like the format of the dumpdb txt file.

I found this e-mail address because 'disabled' reports it as 
"Mailman.Errors.NotAMemberError" every morning :/

Thanks,
Tim H.
