[Mailman-Users] Remove / Strip Sender Signature Question

[Artabase]

Hi All

I searched archives and checked faq but couldn't find this, apologies if
I'm keyword 'tarded this morning.

Is it possible to strip the Sender Signature?

Our lists are subscribed to some other lists, and we're having problems
with members unsubscribing us from those lists instead of unsubbing from
ours.

Thanks in advance, any help appreciated,
