Hello Jocko64,
It sounds like you are unable to send email from your Mail account and you have already used the Connection Doctor to help troubleshoot. Based on that, I would next remove the email account:
Open Mail (click it on the Dock or open it from the Applications folder).
From the Mail menu, choose Preferences..., or press Command-, (the Command and comma keys).
Click the "Accounts" icon.
Select the account you wish to remove.
Click the "-" (minus) icon. You will be alerted that "The account's setup information, mailboxes, messages, notes, and to do's will be deleted permanently from your computer."
If you are sure you want to remove the account and email messages from your computer, click "Remove" to complete this process.
From: Configuring Mail for your email account

Then restart your computer, and re add the account and test the issue again.
Open Mail (click it on the Dock or open it from the Applications folder).
If the "Welcome to Mail" assistant does not appear, choose Add Account from the File menu.
Fill in the Full Name, Email address, and Password fields.
Note: Your email account password will be stored in Keychain to allow you to automatically log in to your email account when you open Mail.
Deselect "Automatically set up account" if it is enabled. Click Continue to proceed.
Choose the proper Account Type.
Give your account a useful description, such as "Anne's Gmail account" or "Juan's Yahoo! email account". It can be called whatever you want.
Enter your Incoming Mail Server, User Name and Password. Click Continue to proceed.
If prompted, enter your Incoming Mail Security settings. Click Continue to proceed.
For Outgoing Mail Server, a useful description such as "Gmail Outgoing Mail Server" or "Yahoo! Outgoing Mail Server".
Enter the Outgoing Mail Server details.
If necessary, select "Use Authentication" and enter your User Name and Password. Click Continue to proceed.
If prompted, enter your Outgoing Mail Security settings. Click Continue to proceed.
Verify your settings in the Account Summary. Check "Take account online". Click "Create" to complete the process.
Thank you for using Apple Support Communities.
Take care,
