Can't send emails due to an error for the outgoing server

Rino Marsala

I currently have spectrum service and have gone through this with them. Everything is fine on their end. TB is throwing this message when I try to send an email.

"Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.twc.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again."

It all worked fine until last week.... Once this started, I changed all servers / ports etc to the settings Spectrum suggested to no avail.

Any ideas?

There have been major problems with Spectrum/Charter/TWC lately. Neither mail.twc.com (TWC's email servers) or mobile.charter.net (Spectrum and Charter's servers) appear to be online right now and may have been down for some time. From what we hear from their users, service has been intermittent for a while but it's gotten worse in the past week or two. It is not specifically a Thunderbird issue - it appears to affect all 3rd-party email clients, including Outlook, EMclient, etc. Spectrum's support don't admit to any problems, only saying that they only support webmail.

Here's a link to Spectrum's own user forum where you can see many discussions of the situation:

If you have time, you should contact Charter for status.
