FAQ: Failed to resolve server address.

This entry in the Event Log may appear for a number of reasons:

To Exchange

If the category for the entry in the Event Log is To Exchange then eXchange POP3 cannot find your Exchange Server.

In the eXchange POP3 administration program go to

eXchange POP3 Configuration Exchange Connection

Verify the IP address or TCP/IP name for the computer running Exchange Server is correct. Also, verify the port set for Exchange's SMTP server listens on port is correct. This value should be:

25
- if running eXchange POP3 on a different computer than Exchange Server
- if running eXchange POP3 on same computer as Exchange Server 2000 or later

8025
- if running eXchange POP3 on same computer as Exchange Server version 5.x or earlier

If this does not fix the problem, verify that Exchange Server is running.

In Exchange Server 2000 or later verify the Default Virtual SMTP Server is running.

In Exchange Server 5.x or earlier verify that the Microsoft Internet Mail Service is running.

Outgoing Mail

If the category for the entry in the Event Log is Outgoing Mail then eXchange POP3 cannot find your Internet Service Provider's SMTP server.

In the eXchange POP3 administration program go to

eXchange POP3 Configuration Outgoing Mail

Verify the field Server (SMTP) contains the correct TPC/IP name for your ISP's SMTP server.

If you have chosen to Send Messages Direct, then verify you have entered the correct IP address for your DNS server. If it is correct, then the problem is most likely a user trying to send to an invalid domain or a domain where their server is down temporarily.
