[Mailman-Users] NNTP gatewaying

I just set up Mailman 2.1.5 with the intention of utilizing the NNTP/Mailman gatewaying process.

From what I see, it doesn't use any authentication. The server we're using on the other side is Typhoon, and I've asked if it can just permit the IP; however, I'd just prefer to have authentication going on like everyone else.

Did I miss something?

Thanks.
