This doesnt make any sense. Ive looked through headers and as far as I can tell the from address is the subscribed address. Ive had myself and friends on the mailing list try it out and the help command works but not the index command. How could we all be messing up our return addressed? We have tried from multiple addresses from multiple isps. Any suggestions?
Well, although it's possible that the admins command is broken, a test message I just sent to an internal mailing list properly came back with a reasonable list index.
The only thing that I can think of is perhaps there's an issue with case sensitivity in E-mail addresses.
Post the output of 'couriermlm lsub', and the bounce message.
