SMTP Mail Server Password Problem

[pbdave]

I had been using Thunderbird 1.07 as my mail client. Yesterday, I upgraded to Thunderbird 1.5. The installation went fine with one glaring exception. The outgoing SMTP server will not recognize my password. I have gone through the following troubleshooting steps.

- I have deleted and re-created the account in Thunderbird
- Had a new password created by my service provider.
- Used my old PC to send an email with the new password. It worked fine.
- Connected to the router with an Ethernet cable instead of the wireless network.
- Uninstalled and re-installed Thunderbird
- Uninstalled Thunderbird and tried to use Mail.app. Mail.app has the same problem, it cannot connect to the mail server.
- Checked the passwords in Keychain.
- Tried connecting through Port 587
- Logged into an SMTP server of a university through Terminal.
The SMTP server responded just as the guide said it should. (found a troublesooting guide for students on the web)

When prompted to enter the password for the SMTP server, I get error messages. Because the email app on the same account on my PC works, while on the same home network, I am inclined to think that I have done something to my Mac when installing Thunderbird. It's almost like I have corrupted SMTP or somehow fouled port 25

My system is a Mac OS X 10.4.4, Powerbook G4.

Any help you may be able to offer would be greatly appreciated.

thanks

Dave

I don't know Thunderbird. I had a similar problem in Eudora when my ISP changed servers. I found that the new server didn't want the "allow authorization" box ticked in the "Sending Mail" preferences. Maybe the upgrade sets this by default?
