Changed Email Hosts and now Unable to send Outgoing Email

[Woodcycl]

I'm a bit stumped on this one. Here's the story:

I moved a website to a new host. The email went thru the host using the domain name. The emails were setup in Outlook via POP successfully.

After the host change / nameserver change, the emails were setup on the new host. I ensured the MX Records reflected the new host.

The Good:
- Webmail works for incoming and outgoing
- POP'g in gmail works for incoming and outgoing
- Setting up POP in Outlook on ANOTHER COMPUTER works for in & out

The Bad:
- Outlook on the MAIN COMPUTER does NOT work for outgoing / smtp.

This leads me to think it is a problem just on that one PC given the "Good" items above.

I removed the email accounts from Outlook.
I removed the email Profile from Control Panel / Mail
I re-created the profile name
I re-created each of the email POP accounts in Outlook in the new profile

Still, Outlook outgoing/smtp comes back with an error. I don't have the exact error yet to post here, but I'll Edit this post and include it shortly. Basically, the smtp server can't be found. I don't think it was a login authentication / verification issue.

The hosts states the pop and smtp mail servers should be: mail.coffeenewslouisville.com. But, I also tried smtp.coffeenewslouisville.com as well with no luck. And, I tried both unsecured and secured (SSL) ports with no luck. The server does require authentication and I tried that, even re-entering the login credentials to no avail.

Again, keep in mind ... outgoing DOES WORK in webmail, gmail, and Outlook on a different computer.

Should I uninstall and re-install Outlook? It is Outlook 2003 btw.

Any thoughts?

Are all the computers at the same location running through the same ISP?

You could change the SMTP info to match the IPS's SMTP info...

Many ISP's don't like you to send from a different SMTP to avoid massive spamming.

The server says you've exceeded your bandwidth limit. Does the mail still work on the other computer?
Have you tried port 26?

Thanks for the tips. In the end, I was considering rebuilding anyway so that is what I did. And, as soon as I attempted to setup Outlook, it began working as hoped.

Very very strange! I have never run into that. Something must have been cached or similar on that PC.
