Daniel,
Thanks for your answer yesterday to the control access question. I re-installed into
d:\imail instead of d:\Program Files\imail
Anyway now that I've got it working I'm not sure it was what I wanted anyway. I'm
trying to secure the Imail Server against spam. We
are a web design company who own our own server and host our customers domain names.
Now we use the Imail server to forward emails
onto our clients ISP's. We don't allow them to dial up and access our server. We also
use the Imail server for our own email system,
that is dialing direct into the Imail server to download the company emails. Each
company employee here has their own mailbox. We
have the SMTP Security set to 'Relay for local hosts only' which seems to work fine
except that one day a while ago, when we were
inadvertently running an open relay, we were reported and tested by www.orbs.org who
were able to send emails to themselves from our
Imail server thereby adding us to a blacklist of mail servers.
We then changed the SMTP Security to 'Relay for local hosts only' and resubmitted our
server for testing and they were still able to
send a couple of test emails to their system from ours.
For the record when we connect to the server we are allocated a dynamic IP address so
it's difficult to block IP address and let
certain ones through.
We need emails for our clients to get forwarded on and ourselves to be able to send
and receive emails in the office and nothing
else. Everybody else should be denied access to the server.
Can you enlighten me as to what other changes I need to make to make our mail server
secure.
Thanks in advance
Mike Franklin
