Hi, we need a little bit more information to help you, like your mail sending topology eg: my exchange 2003 server >> firewall > internet or my exchange 2003 server >> mail relay (like ironport or anyother) >> firewall > internet does this happen to all your email's ? or only one user ? what version of exchange server you have ? what have you already done to try and troubleshoot ? ** tip , don't post messages like "please help ! urgent !!" it can't help much .. try to post only one relevant post with as much details , and in one place....

Hi,Please first confirm which queue did the message hang.Whether any error message come up in the event log or any NDR was received?Now please try to telnet remote mail server ( f.mx.mail.yahoo.com) 25, what's the result?ThanksAllen

hi,check your mx records, reverse dns records etc...and answer Ilantz' questions about your system...regards,Mumin CICEK | Exchange - MVP | www.cozumpark.com | www.mumincicek.com

Agree with Mumin, Mostly it is an issue with MX record. Please answer Ilantz's question and if possible could you please provide your email domain name?Arun Kumar | MCSE - 2K3 + Messaging | ITIL-F V3

Hi, This also sometimes happens due to not configuring a Send or Receiver Connector for the Exchange environment. Regards, Laeeq Qazi

Hi,Depending on your network setup it could be a firewall setting were you doing a migration or is this a freash build or did it just stop working
