What I meant that how can I stop people replying to e-mails from our
network, given that we don't tag them as spam
Do it in your MTA then... for example Sendmail; /etc/mail/access:
to:[EMAIL PROTECTED] REJECT
to:[EMAIL PROTECTED] REJECT
or
to:[EMAIL PROTECTED] ERROR:"550 Reply to a phishing
drop-box rejected"
That will stop your MTA sending messages out to these mailboxes and
instead the sender will get a DSN with the SMTP rejection text.
Modify to suit whichever MTA you use...
