i am using Exchange 2003 with win2003 R2. i am also using GFI mail essential as CatchALL account to fetch email which is working successfully. But when i want to send email the queue of EXCHANGE keepsmail but not sending outside world. My Exchange setting in the Server-->Exchange-->Protocol-->SMTP-->Default SMTP virtual server-->Properties-->Delivery-->Advance-->Smart Host, in smart host i put the ISP smtp ip ( for example[0.0.0.0] ) and in the Configure i put the external DNS ips. (in smart host i also tried to use my web/email hosting SMTP ip but same problem ) my 2nd question is from where i can check that in which process my email has been got stuck !!! Thanks in advance Haseeb

Finally the problem was with the port of outbond connection in (Administrative Group-->First Administrative Group-->Server-->Protocols-->SMTP-->Default SMTP Virtual Server-->Properties-->Delivery-->Outbond Connection-->TCP port here i put 8025 but here should be 25) http://forums.msexchange.org/m_1800511515/mpage_1/key_/tm.htm#1800511566 Haseeb
