[Mailman-Users] Mailman 2.1.1 list subscription mechanism seems to be broken: please help

[S. Krishnan]

Hi,

I just upgraded my working mailman 2.0.13 install to 2.1.1 by
downloading and installing from source. The previous version worked
fine.  However, 2.1.1 has a major issue with subscription messages. 
Every time someone subscribes to a list, mailman sends them a mailing
list subscription confirmation notice.  With mailman 2.1.1, replying to
this notice does not seem to work.  Instead of confirming the
subscription, it sends *another* mailing list subscription confirmation
notice, with a different number.  Replying to this results in yet
another subscription confirmation notice! 

However, subscription confirmation off the web page works OK.  It is
only the confirmation by reply to the notice that is broken.

Could someone please help?

TIA,

Krishnan
