There are couple of things you should do 1. Check if you can run a telnet session on port 25 of the external ip address of your server 2. If you can successfully do step I then repeat the process again this time using the domain name. If that does not go through then basically you are having a DNS issue, ensure that your DNS entries are well configured. If you are sitting behind a firewall, you might need to enable outgoing SMTP traffic. Lets have a better understanding of your architecture so that we can help you better Seyi _____ From: soso bobo [mailto:soso20052006_4@xxxxxxxxx] Sent: Tuesday, January 04, 2005 3:30 PM To: [ExchangeList] Subject: [exchangelist] Please Help , Please Help http://www.MSExchange.org/ dear All, i have here a problem with my exchange , i can send to all domains , but i have a problem with receving . while i was open my server i found this Error message in front of me :- Microsoft Connector for PoP3 mailboxes has generated an internal error , that it could not recover from, once this dialog is dismissed the following files will be generated :- c:\Program Files\Microsoft Backoffice\connectivity\PoP3 Connector\vmimb.txt c:\Program Files\Microsoft Backoffice\connectivity\PoP3 Connector\vmimb.evt and c:\winnt\drwtsn32.log ========== what do you think the Problem is ? please advice __________________________________________________ Do You Yahoo!?
