"midrange-l" is a correct name of an existing list. "midrange-l__;!!NVq9dfhzMyHqTw!wLl-dt8zxsuQuoyojs-UYmT_d65WZroClHaYGfHduJ561eT0B7baTQV1ogZzQKRRsw$" is not. -thh -- Mailman-Users mailing list -- mailman-users@python.org To unsubscribe send an email to mailman-users-le...@python.org https://mail.python.org/mailman3/lists/mailman-users.python.org/ Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: https://www.mail-archive.com/mailman-users@python.org/ https://mail.python.org/archives/list/mailman-users@python.org/

I don't understand the terms you use. So I will not comment further on this thread. "Web UI"? "Email"? However, I did suggest using Google to find out more about Proofpoint. All the information is there. They do have a goal. Whether they achieve it, I do not know.

I'm pretty sure that this comes from Proofpoint's "URL Defense" system. (Google it.) But I don't understand what you mean by "hostile listname" being "correct". What comes before the __ is usually a URL, and there is also a __ BEFORE the url begins. If you use a graphical mail client (like gmail), you don't see this extra junk, but if you click the url that you see, Proofpoint will check it to see if it is on a list of nasty sites. If you want to see the URL alone with a text client (like mutt), I suggest running all messages through .procmailrc with this recipe: :0 f | /usr/bin/sed -e "s/__/ /g" This will replace __ with spaces, leaving the url itself standing alone.
