Looping, cascading Welcome and HELP messages

[Ben Parker <ben @ dha . unon . org>]

I am using 1.94b3.

I have various subscribers on addresses that generate auto-responses 
(receipts, fax acknowledgements etc). When I join them with a "subscribe 
list address", the auto-reply to the welcome/intro message goes back to 
majordomo, which then sends them help, which generates a receipt, which 
generates Majordomo help, etc etc ad infinitum. Is there any way round 
this? The taboo headers seem only to apply to submissions to lists, not 
to mailings to majordomo itself.

Second question: a command like approve password unsubscribe * address 
doesn't work. Why is that?

Any advice gratefully received...

Thanks
