Well, my server was on the internet. But, it isn't anymore; it's behind a router.
I hate to say it, but you've got a lot to learn.
If someone can send you E-mail from the Internet, your mailserver is on the Internet! Just because it's behind a firewall (it's a firewall if it lets you block all packets except those you want) doesn't mean it's magically off the Internet. It just means that certain activity is restricted. Firewalls are great, but very few will do anything to combat spammers.
And the fact is this: If you are listed in DSBL (or one of the other spam databases that lists open relays), you've got a mailserver that spammers can send from. It's that simple. DSBL doesn't just randomly add IPs. Although it is a "dubious honor" being listed by DSBL, it does mean that spammers can use your mailserver for free. It shouldn't be ignored, unless you *know* (not think) that spammers really can't use your mailserver.
Imail should only relay messages that come from servers on my LAN behind the router. So, my server shouldn't be a spam threat. Am I missing something?
Yes, you are missing something. It doesn't matter what IMail is supposed to do or should do, or what you think it is doing. What matters is what it does. It is (or was) relaying. I'm not going to do your job and go to the DSBL site to see when you were listed and why -- if you don't care, you don't care, and my extra effort isn't going to help you. You're convinced that you aren't an open relay, even though someone has proved that your are (or were).
I'm still not seeing where the Relay for Addresses is found.
And you wonder why your mailserver is free to be used by spammers? You wonder why IMail is relaying messages from outside your LAN? You've got just enough knowledge to be very dangerous. You keep saying that you are sure that you aren't an open relay, but keep disproving yourself. :)
I have Imail 7.13. I'm looking under services at the various choices for SMTP. Is that
the place?
Yes, it's found on the "SMTP Security" tab.
