FAQ.

What you want is Relay mail for Addresses. Put in your addresses only.

Everyone that isn't in your LAN (all your clients) will have to log on to
the server with their POP3 user name and password before they can send
email. Since this is available in every major email program this shouldn't
be a problem.

There is no other setting that will prevent your server being used to send
spam from the outside.

Maybe if I explain my situation a bit, you might be able to tell me what am
I doing wrong.

We have over 100 customers coming from different networks.
We have over 100 web sites using CDONTS or FPSE to send email from the web
site (relaying it through the Imail server).

When I choose the no mail relay, I can't seem to send mail out at all - even
from my client ( I am on a different IP network). I know that I can specify
which Ips are ok to relay, but with over 100 customers, I can 't specify Ips
one at a time.

I have the feeling that when I choose this option, mail can not be sent out,
even from users from Imail (our customers).

Thank you for all of your help.

Note that any setting other than "Relay for Addresses" and "No Mail Relay"
means that you are an open relay, allowing spammers to use your service for
free.  That's probably why you are listed in NJABL, ORBZIN, and ORBZOUT.

>setup to relay email only for local hosts).

Well, any spammer can do that, unless you use "Relay for Addresses" or "No
Mail Relay".  So don't worry about it too much.  If you really want to be
an open relay, and care how it is open, you should make sure that you
stopped/restarted the SMTP service.

To make sure that you are not an open relay, you can either use IMail's
"Relay for addresses" (in which case you would enter a list of "safe" IP
addresses that your users may come from; anyone not coming from those safe
IPs would need to use SMTP AUTH), or "No mail relay" (which really means
that everyone must use SMTP AUTH).  Note that relay setting apply only to
outgoing E-mail, so no matter what your settings are, your users will still
be able to get mail.
