I think I have the idea now but I'm not there to check it out at the
moment...

I need to do something like the following:

On the local mailserver, I need to set up accounts for each of the email
users.  eg.
cod at server.cod.ie
jp at server.cod.ie

I need to set up fetchmail to map the external email addresses to the
internal ones so:
conor.daly at oceanfree.net -> cod at server.cod.ie
jon.peterson at oceanfree.net -> jp at server.cod.ie

I need to run a pop daemon on the server

I need to have the clients get their email from "pop.cod.ie" and login as
their server usernames ie.
for conor.daly at oceanfree.net I pop mail from "pop.cod.ie" as user "cod"

That takes care of the incoming mail.  For outgoing, I need to do the
following:

Run an SMTP daemon on the server.

Point my clients to "smtp.cod.ie" as their smtp server and have them just
set their email address as their external one.

Let sendmail know that mail from conor.daly at oceanfree.net is to go to
mail.oceanfree.net and here's the username and password to use.  This seems
to be the tough one.  I'm not quite sure how to get sendmail to understand
that.  Should I have users send mail as localuser at server.cod.ie instead and
do a reverse mapping as for fetchmail or is this step not necessary?

I presume all I need to do to create "pop.cod.ie" and "smtp.cod.ie" is to
set aliases for them in my DNS.


Thinking hard and no server to play with...
