Check the outgoing server smtp settings.

In Account Settings Left Pane scroll to the bottom below 'Local Folders - click on 'Outgoing Server (SMTP)' You should see a list of outgoing servers ont he right

select the outgoing server in list Do you have the following details because this is what you need:

• Description : full email address
• Server name: mobile.charter.net
• Port: 587
• Connection Security: STARTTLS
• Authentication Method: Normal Password
• User name: full email address

If you need to edit anything - click on Edit', modify anything required and click on 'OK'

then check you are using that smtp in the account So still in Account Settings In Left Pane, select the name/email address of account Look bottom right for Outgoing Server (SMTP) Does it say the full email address as you typed in the smtp description ? If no, then click on the drop down to see options and select the correct smtp server. DO NOT click on 'Edit Server_SMTP' button.

Thanks for the reply. I was able to figure it out yesterday morning. All of connect security, even from Spectrum, was saying SSL/TLS.

I then found a site that said it was STARTTLS and everything was working again.

Don't know why it was working up till 6/13/23 and then all of a sudden stopped.

I did not change anything and got no notifications from Spectrum about any changes.

But, it is working now. Just a minor inconvenience.

Thanks

Bob

For my desktop: I solved this by Changing the outgoing Server (SMTP): back to the default setting of Charter Communication - mobile.charter.net. I believe Thunderbirds update switched "mobile charter.net
