Hello Lalonzo,

First of all, you are using the wrong configuration for sending out mail. POP3 server is meant to receiving incoming mails and therefore when you use it for outgoing mails it will not work just like it is not working right now for you.

You will need to change your configuration and use SMTP server for outgoing mails on your ms exchange, configure the pots properly and then test it by trying to send out a mail. See the messages will be delivered to the destination this time round.

Hope this helps.

If your computer cannot send an email message using the POP3 protocol on Microsoft Exchange Server 2003, your Exchange Server is probably not configured properly. Microsoft Exchange Server 2003 is very capable of using the POP3 protocol. Here’s how to fix your problem. Before doing this, make sure you are using an administrator account on the Exchange Server and your account is a member of the local Administrators group.

To enable POP3 access to Microsoft Exchange Server 2003, run the following command in the Exchange Management Shell:

Set-PopSettings -ProxyTargetPort 110

The default port value is “110” and by default you should set the port to this value. After running this command, you need to restart the POP3 service. For those using Microsoft Exchange Server 2007, POP3 is disabled by default. To restart the POP3 service, go to How to Start and Stop the POP3 Service for the complete instructions.
