>Is Abuse.net's test adequate to rule out an open mail relay problem? It's pretty thorough, and most MTAs have default configurations that don't permit relay, so it's much less of a problem than it was when I wrote the tester many years ago. I don't try to check for weak SMTP AUTH passwords, a hole that some spamware exploits, so if you do AUTH, it's conceivable that could be it. In your case, though, I would wait for the complainer to forward you a message or two with headers so you can figure out where is spam is coming from.
