Hi all:

Is there a way to have couriermlm require "subscribe" or some such thing in the subject or body of a subscription email? What I'm seeing is ton's of spammer's email going to my <maillist>-subs...@foo.bar.com. For the non-moderated lists, this is fine, but for the lists that require approval before the subscription is accepted, it's a real pain. Fully 99% of the subscription-requests I'm getting are from spammers. I'm thinking if it checked for the word "subscribe" or some other such word in the body or subject line, it would filter all that crap out.

I don't have a problem going in and hacking away as the couiermlm code, but wanted to check to see if somebody had done it already before I jump into it.
