Mailmane error after VERP_CONFIRMATIONS change

Mailman error after VERP_CONFIRMATIONS change

I recently had a configuration change made in my mailman software to enable more user friendly subject headers for invitations to email lists on my server. This is the change that was made.

Code:

# For nicer confirmation emails, use a VERP-like format which encodes the
 # confirmation cookie in the reply address.  This lets us put a more user
 # friendly Subject: on the message, but requires cooperation from the MTA.
 # Format is like VERP_FORMAT above, but with the following substitutions:
 #
 # %(confirm)s -- the list-confirm mailbox will be set here
 # %(cookie)s  -- the confirmation cookie will be set here
 VERP_CONFIRM_FORMAT = '%(addr)s+%(cookie)s'

 # This is analogous to VERP_REGEXP, but for splitting apart the
 # VERP_CONFIRM_FORMAT.
 VERP_CONFIRM_REGEXP = r'^(?P<addr>[^+]+?)\+(?P<cookie>[^@]+)@.*$'


This line was    

    # Set this to Yes to enable VERP-like (more user friendly) confirmations
    VERP_CONFIRMATIONS = No

changed to this

    VERP_CONFIRMATIONS = yes

Now, when trying to edit the public HTML pages, all of the lists created prior to the modification are
creating the following error message. Lists created after the change do not appear to be affected

Code:

According to this entry in the mailman archives

http://www.mail-archive.com/mailman-users@python.org/msg28295.html

and this faq entry


http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq06.011.htp


the problem apppears to be a conflict with cPanel

Is there some sort of fix for this or am I going to have to undo the changes to make the old lists work properly?

Thanks in advance for any help

Bill
