Each message starts with a line like "From mailman-users at python.org",
so you can just count those. Divide by months in file to get messages/
grep -c "From <list>" <file>
For the mailman archive, this works:
grep -c -i "From mailman-users at python.org" mailman-users.mbox
After some thrashing, the number is:
C:\docs>grep -c "From mailman-users" mailman-users.mbox
2721 lines match
The space is important: lots of header lines have "From: ..."
