Procmail usage?

[Alan Murrell]

Hi Thomas.

Thank you for the reply.  I have a question or two for clarification, if you 
do not mind...?

This seems to be rather straight-forward...

  1.) Is is possible to use something like "@example.com" to enable all mail 
for a domain to go through procmail, or does it have to be individual email 
addresses?

  2.) In the above example, why does "the.user.one at example.com" get put 
through "procmail-user" instead of just "procmail"?

OK, so in my setup, all users will have an @murrell-van.local email address, 
with an email alias consisting of an @murrell.ca address (i.e., a 
"real-world" email address)

My transport.template file should have something like:

  user1 at murrell-van.local     procmail:
  user2 at murrell-van.local     procmail:
  user3 at murrell-van.local     procmail:

and so on.

Could I then use the @murrell.ca address to have the email re-injected into 
Kolab by forwarding the mail to that address in procmail, even though it's 
setup as an alias?  If so, I am guessing I would then need to also add 
something like this to the transport.template file:

  user1 at murrell.ca     kolabfilter
  user2 at murrell.ca     kolabfilter
  user3 at murrell.ca     kolabfilter

and so on.

Does it matter which email address I designate to go through procmail and 
which one I forward to back into Kolab via procmail rules?

(I hope this makes some sense...?)

Thanks, once again. :-)
