I apologize if this is not the most appropriate newsgroup
for this post.

I have two questions about Mail that I could not answer
by looking to documentation available to me or by asking 
people around....Maybe someone here could help.

I wanted to know  whether it is possible (and in  case it is how) 
to set  things so that mail from a specific "userid" or from
a certain host gets automatically deleted. Something similar to
a "kill file". Also, is it possible to automatically return 
every message from a *certain* user or host??

I use a UNIX system, and Mail version SMI 3.0. 

If the answers are too trivial and/or do not "belong" to this
newsgroup, please e-mail.

Thank you very much for any help.
