That isn't easy to do. The problem is that usually the only information you can get is from the server at the final destination, which is "innocent" (the guilty party is the mail server that you sent to). If the bounce message includes the full headers of the original E-mail, you should be able to determine what mail server the E-mail was forwarded from. From that, you can search the IMail logs to find out which user(s) it could have been sent to, which could be a time consuming process. >I haven't been able to find anything in the headers that will help me >(possibly because we're still using version 4 of IMail . . .). v4? I had almost forgotten there was such a thing! :) >On a side note, I noticed something interesting in my logs today: > [208.11.217.254] connect 152.163.224.70 port 50211 > [152.163.224.70] HELO Open_Relay_Test_ort-r01.mail.aol.com > [152.163.224.70] MAIL FROM: <[EMAIL PROTECTED]> > [152.163.224.70] RCPT TO: <[EMAIL PROTECTED]> > [152.163.224.70] ERR clinres.com invalid user ><[EMAIL PROTECTED] >I guess AOL is looking for open relays on their own.
