[Mailman-Users] email subscription sends two messages

[hone+mailman at oak.cats.ohiou.edu]

Using Mailman version: 2.1.9

I sent a subscribe command to join a listserv and received two confirmation 
messages. Could this be the result of putting the word subscribe into the 
subject as well as the body? If not, any other ideas?

Could this be a bug or should we use only body or subject?
