This is not a new problem. It has happened for a long time, probably for all the years I've had the classifieds installed but I've finally reached the point where I'm getting tired of it.
I'm running Classifieds version 4.1
When one of my users posts a classified ad, I usually get this email. I've replace the actual username with the XXXX.
Now, I don't think it happens EVERY time but most of the time. I also wonder if it has something to do with my VB3 integration. I'm not sure but it may be happening when a member posts an add that hasn't actually registered in the classifieds. With my integration though, shouldn't all my members be automatically registered as classified users? If so, then something is wrong because I have about 11,000 registered forum members but only a few hundred registered classified users.
Anyway, here is the message that I get about the bounced email.
