What is the sender signature?

Do you mean that your list is subscribed to some other list, and the
other list adds a footer similar to the following:

>------------------------------------------------------
>Mailman-Users mailing list Mailman-Users at python.org
>http://mail.python.org/mailman/listinfo/mailman-users
>Mailman FAQ: http://wiki.list.org/x/AgA3
>Security Policy: http://wiki.list.org/x/QIA9
>Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/
>Unsubscribe: http://mail.python.org/mailman/options/mailman-users/yourlist%40yourdomain


and then members of your list see that footer, follow the Unsubscribe
link, request unsubscription, and then receive the confirmation (sent
to your list) and confirm the unsubscribe?

If that's what you mean, you have a couple of choices. Mailman has no
facility for removing that footer from the post to your list, but you
can add your own footer with a message something like

DO NOT USE THE ABOVE LINK TO UNSUBSCRIBE!
To unsubscribe from this list, go to http://... or send a blank email
to yourlist-unsubscribe at yourdomain.

Or you could add header_filter_rules to your list with regexps like

^subject:\s*confirm [0-9a-f]{32}\s*$
^from:.*-confirm\+[0-9a-f]{32}@

and an action of Discard to prevent the confirmations from reaching
your list.

Of course someone with intent to unsubscribe your list from the remote
list could always request a password reminder from the remote list
which would be posted to your list, and then use the password to
unsubscribe without confirmation.

You could add

^subject:\s*[^\s@]+@[^\s]+\s+mailing list reminder\s*$

to the regexps above to stop the password reminders too.


If the above is not the scenario that you are encountering, then please
be more specific about exactly what it is.
