I have tried as a new user but still can't send. I checked and created a new
account in Entourage with the correct smtp settings but still no luck.
Keychain appears to be ok.
Could there be a hardware problem?
Going back to your original message. You said "It is strange that even
webmail does not send. Any ideas?"
Let's check your System Preferences --> Network to be sure they are set
correctly.
What happens when you use your browser to view the web?
You also said "recently downloaded and installed upgrade 12.01.1. Since
installing I am unable to send email via ethernet cable.". Was Entourage
working in 12.0.0?
If System Preferences for Network are correct, try entering the same info
into Apple Mail. If it works there then you know the setting are correct. If
they do not work, then it's your settings. Are these old accounts that
worked with the info before?
I seriously doubt it's a hardware problem. Below are the basics. Testing in
a new User eliminated your keychain, but it does not eliminate user error
like adding a space or having the wrong info and/or selecting the wrong
choices.
1. If you can receive but not send then you have a bad SMTP configuration
2. If you can send but not receive you have a bad POP or IMAP configuration
You can try re-entering info.
You can delete account and create a new one.
Using copy/paste can result in an extra space being added. Type carefully.
Check your Keychain for corruption.
I would also apply the Apple Leopard combo updater. Doing so overwrites
potentially problem-causing files. Several users have reported this fixed
some odd problems they were having with Entourage. Combo updaters will
install on the same version as they¹re applying‹no need to roll back or do a
clean install.
