Hi
I am beginning to pull my hair out here, I am still pretty new at EXIM and I am suffering from MASSES of "message frozen" responses.
the issue seems to be when a message is returned to my domain, to a user that doesn't exist.
Now, I am not yet sure WHY the messages are coming back to me - whether it is faked FROM by a spammer, or somebody careless joined a mailing list using a fake email address, that happens to be in my domain - OR - my fear that I am actually OPEN as a relay and being used.
Either way, there are lots of them, and I am strugglying to see how I can prevent them, and how I can reduce the load on my server and link.
I am guessing that exim can do something like Original From != From != HELO domain... but I don't think that is sufficient. Ideally I'd like to block these at the SMTP handshake stand. Or am I just going to have to get used to them
My theory goes along the lines that if I can make an expression out of these bits I might be able to block it... but since part of this is the original included message it may not help
