I have a user trying to email someone at UIUC. Here is the error generated:
Connected to 128.174.5.12 but sender was rejected. Remote host said: 451 4.1.8 Possibly forged hostname for 208.100.1.33 I'm not going to try again; this message has been in the queue too long. I call in and they tell me I need to fix my reverse DNS. They're the first ones to have a beef with it, so I contact my provider to have him change the reverse DNS to ics-il.net, which is the domain my client is mailing from. Now I get this error: Connected to 128.174.5.120 but sender was rejected. Remote host said: 550 5.7.1 Fix reverse DNS for 208.100.1.33 Ideas? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -------------------------------------------------------------------------------- ** Join us at the WISPA Reception at 6:30 PM on October the 16th 2007 at ISPCON ** ** ISPCON Fall 2007 - October 16-18 - San Jose, CA www.ispcon.com ** ** THE INTERNET INDUSTRY EVENT ** ** FREE Exhibits and Events Pass available until August 31 ** ** Use Customer Code WSEMF7 when you register online at http://www.ispcon.com/register.php ** -------------------------------------------------------------------------------- WISPA Wants You!
