You have now closed your relay. That's what I would have thought, too, but this morning I found that a spammer had used my SIMS to send out a few pieces of spam which SIMS delivered. The "Relay for Clients Only" box is checked (as it always has been) but the "Verify Return Paths" checkbox was not. I have since checked the latter box, and have seen no spam go out since then, but that doesn't mean it made any difference since the spammer's machine tried many times before succeeding anyway. So, where can I look to see what else I may have missed? The correspondence between my server and the spammer's machine (bounce.em5000.net) seems to have mentioned an unused IP address that's on my server. I can't tell if the spammer is using it or how it even could. That IP address is on my SIMS client IP list. I have no idea how to tell from the log or from the message queue what the IP address of the spammer's machine is. Anyway, if somebody can help me understand what else I need to do or check, I'm sure the information would be useful to others reading the list who are just starting out with SIMS. I've been reading this list for a long time, and now that I've actually got SIMS running, I get surprised.
