Receiving e-mails. When I try to send, there is a long pause followed by an error message; Sending message failed. the message could not be sent because the connection to outgoing server (STMP) [mail.Brighthouse.com](http://mail.Brighthouse.com) was lost in the middle of the transaction. Try again

Did you try again?
The connection being lost in the middle of the transaction indicates a problem in routing to me.

Yes. Multiple times. Re-install, reboot, etc. Also, it appears that when I click on “Get Messages” there is no response. The messages just appear when I load Thunderbird or when they arrive.

What are the outgoing settings? They should be [mail.brighthouse.com](http://mail.brighthouse.com) on 587, SSL/TLS, normal password, email address for User Name.

Most providers require STARTTLS on 587, but not Spectrum. Select SSL/TLS first, then type in 587 for the port.
