[Mailman-Users] Newbie with error...

[Jorge Biquez]

Hello all.

I'm sure this has been asked before...looked on the archives, found some 
tips but the problem is still here....

I installed, following all the steps I guess.... on two different machines 
and in both I'm making the same mistake.... after creating a list with 
bin/newlist when a user send an email I received the answer:

	550 5.1.1 <prueba8 at pruebas.validomain.com>... User unknown

I have configured in two systems. One a freebds 4.5 stable using sendmail 
and the other a Linux Mandrake 8.1 using postfix. All both equipments do 
the same... I can see the administrative webpages, change parameters and 
everything.
I read on the archives that I need to be sure that aliases is corrected 
written and updated with "newaliases"

Do I have to create a user each time I create a list (in this case prueba8 ) ?

Thanks in advance for all your help and I'm sorry if this question sound 
stupid....maybe it is..... ;)
