Problem configuring MailEnable to work with Outlook Express

[Discusman]

Hi guys,

I'm trying to set up mailenable on my server as an email server.

The mail client that I'm using is Outlook Express.

It prompts me for username and password when every time I start Outlook. Why? I didn't set up password in MailEnable.

Then if I click on Send/Receive button in outlook. It gives me an error saying "There was a problem logging onto your mail server. Your Password was rejected. Account: 'mail.mydomain.com', Server: 'mail.mydomain.com', Protocol: POP3, Server Response: '-ERR Unable to log on', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC92"

I ran analyistical utility in MailEnable. I found two failed test

1. Local Mail Domain Resolution Test (nyc-discusfanatics.com)

Error: Could not resolve your Local Domain Name in DNS. You should change the local domain name to a domain name that is registered in DNS. This setting is found in the MMC under the properties of the SMTP Connector.

I don't understand this error since my registered domain name is nyc-discusfanatics.com and it is my local mail domain name.

2.Could not resolve DNS. (1460)

The DNS settings used by the SMTP Connector have caused tests to 'Fail'. Some diagnostic tests have been skipped. Please review your configuration and re-run this utility

I also tried this in DOS such as

telnet mail.nyc-discusfanatics.com

It went through without a problem.

It gives me a welcome message..

What is going on? Please help.

I'm using Windows 2003 and it is a fresh installation. I haven't installed IIS yet.
