Hi , There is No problem with SMTP service ...Everything is fine And they are able to send Emails to Other Domains too..Except AOL & Yahoo. When they will be sending Email it is going with 123@xxxxxxx (service provider Gateway Ip address x.x.x.x) . So they Have Blocked the Ip address not the domain name. Pls advise me how to do ? wht to do ? Thanks in advance.....

If those flows smoothly then you know AOL or Yahoo have put that domain on black list?Else you need to make sure that SMTP service is running properly and have configured OK.

As I suggested they have tried changing Gateway it went out but very slowly, Yesterday again they faced the problem. And this time it was problem only with sending Emails to Yahoo and AOL Domains. tried using Another Exchange Server which we build for testing from there also we are unable to send mails to Yahoo and AOL. And I found it the ip address they are using is in spam blocked ip ..and tht ip doed not have reverse dns entry... Please let me know whts the permanent solution and one more thing This server is our Internal mail server & SMTP server (abc.com) ...and already we have Other External mail server which will respond in the internet (abc.com) now how to set Reverse dns for exchange server And if we set is there any problem to the external mail server (Linux) .. Thanks in advance.....cheers ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp ------------------------------------------------------ Visit TechGenix.com for more information about our other sites: http://www.techgenix.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: sunny@xxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp ------------------------------------------------------ Visit TechGenix.com for more information about our other sites: http://www.techgenix.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: prkamuni@xxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx
