well, just leave the single machine that connects to it on then.
I cant see how you can POSSIBLY manage 90 users on ONE mailbox though..
At least with clara you can set up 90 mailboxes and all the normal
aliases that might be used, and reject the rest with 'addressee not
known' or what ever.
When I first started my own domain I used to get FLOODED with email for
another company with a similar name. For two years I dutifully forwarded
all these on to them, and asked them time and again to get their
customers to use the correct addresses, and then to fix their OWN sender
addresses so they weren't in my domain.
They thought this was all my problem.
In the end, I cut the thing down to must me at my domain, and rejected
the rest with 'if you are looking for XYZ, the domain is actually xYZ'
and gave up.
Basically you are using the wrong tools for the job. If you HAVE a mail
server, it should be on 24x7, and it SHOULD be really running SMTP, not POP.
As far as making it inaccessible to the net in general, that's what
firewalls and mail rules are for. Almost any decent mailer will be able
to recognise 'apparently internal sender, but from external source', and
reject it as relay abuse.
Even if you stay with POP, the answer is leave the mail server on.
