dovecot - Aug 2005 - public/private email accounts

Hi,

I am running FC4 with postfix/dovecot/amavisd-new etc on my box with 50
staff email accounts (say 10 per 5 departments)... everything is working
ok...

I want to create 5 more accounts for each department (to be redirected to
respective staffs, e.g. sales at xyz.com) as well one for everyone... that
can be easily done by creating an account and modifying the .forward file
in the /home/<user> folder.

My great concern is that if by a virus attachment or spam is not detected
and sent to everyone at xyz.com, it will be replicated to 50 email
addresses... what I want is to have the 6 accounts mentionned above to be
used only by the personnel and not the outside world... is there a way of
doing this?

Thank you.

Yes.
However thats a mail delivery issue and will need reconfiguration of
your MTA (postfix in this case).  I suggest you ask on a list
appropriate for that.

[BTW Don't get hooked up on having a real account complete with home
directory and forward file.  The traditional way of doing this is to use
aliases, and in exim (mentioned because its the MTA I work with) you
would have a set of group aliases in a router with a condition on it to
ensure only legitimate users could send to it).]

An alternative method would be to use a full scale MLM (Mailing List
Manager) such as Mailman ( http://www.list.org/ ) but this is almost
certainly serious overkill for your environment.
