[Mailman-Users] Self Subscription Failing

[Troy Knabe]

We use mailman primarily for internal mail lists, but recently I had a
request for an external lists that users could subscribe/unsubscribe to via
email listname-join, etc.

When I send to listname-join I see an entry in the subscribe log for
listname: pending emailaddress, but the user never receives the confirmation
email.
