[Mailman-Users] Amount of messages in a .mbox file

[Jon Carnes]

Just to be on the safe side I use:
  grep -c ^"From " <listname>.mbox

To separate them by Month use something like:
  grep ^"From " <listname>.mbox |grep -c " Mar "

The months are: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov,
Dec.

Good Luck
