[Mailman-Users] Two sub/unsub confirmations sent

[Steve Thomas]

Background...
 RedHat 9, kernel 2.4.20-27.9
 Mailman 2.1.1
 Exim 4.3

I've googled for the answer to this and I've been lurking on the list for a while but haven't seen/found anyone having the same problem. If I just missed something, feel free to flame but please point me to the post/thread/faq.

Everything's working fine (sub, unsub, posting) *except* that when someone sends a subscription or unsubscription request, they recieve two separate confirmation messages. The messages use two different unique tokens, as if two separate subscription requests were sent.

This only happens with requests sent via e-mail; requests from the web form work as expected. The exim logs (below) show that it's only delivering one message to Mailman, but Mailman is sending two responses. I can post the exim router/transport if necessary.

I've gone over the settings in mm_cfg.py and didn't see anything that could be causing this problem.

Anyone know what the problem could be?

Thanks,
Steve
