All of a sudden, can't send email via Thunderbird

This afternoon when I turned on my computer, I had no internet connection. After following Charter/Spectrum's instructions, I got connected, and downloaded my emails. I got them fine, but when I try to reply or send a new email, I get the following error message:

An error occurred while sending mail: The mail server sent an incorrect greeting: impout002 charter.net MTM3LjI1LjMyLjgy You must connect from Charter IP space. E1110.

I have changed nothing in my email settings. I have the correct STMP setting (smtp.charter.net) on the outgoing server for my Charter email address. If I log into spectrum.net and use the email utility there, I can send and receive emails just fine. It's only from Thunderbird that I can't send emails and receive that error message.

I also use Thunderbird for my gmail account, but I think that uses stmp.googlemail.com (although stmp.charter.net is the default). I can reply to or send new emails out via gmail using Thunderbird with no problem.

I've rebooted the computer, but that hasn't resolved anything. Spectrum says that because I can send emails via their site, they can't help.

I'm really hoping someone here can, however (help, that is...)! Thanks in advance.

Chosen solution

'Incorrect greeting' happens when you have the wrong server or wrong settings. Try this for the outgoing server: mobile.charter.net on port 587, SSL/TLS security (not STARTTLS), normal password authentication, User name = email address.

SF, does it matter that I'm on a desktop and not using a mobile device?

First, thanks for your help so far!

OK, I set that as default, but I did not delete stmp.charter.net and still got the same error message. Then I deleted that and made the mobile.charter.net the default. It tried to send a test message, but got the following error message:

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mobile.charter.net timed out. Try again.

I did try again, with the same result. Any idea why this is happening?

My incoming messages are arriving fine, so I'm reluctant to mess with them, unless you feel it would affect the outgoing emails.

I don't believe I have an anti-virus program scanning OUTGOING mail, but before you suggested the settings you did, I'd had Security Connection set to "none." Just for the heck of it, I reset it just now to "none" again and tried to send an email - same result, connection timed out.

I looked at the Outgoing Server information; gmail is definitely going out on stmp.googlemail.com, and charter is set to go out on the default, which is now mobile.charter.net. I just looked to see if I could delete the default and just use mobile.charter.net without designating it as the default, and the delete button is inoperable when I highlight mobile.charter.net - I know that wasn't the case when I deleted stmp.charter.net, so not sure why I can't now delete it and remove its default status.

By now, I'm sure you're as frustrated as I am, but if you've got any ideas, I'm happy to try them! Thanks for hanging in there with me.

Victory!!! Thanks, sfhowes, for hanging in there with me on this irritating problem - retyping the port did the trick.

What specifically did you do that fixed it? Thank you!

I'd already changed the outgoing server to mobile.charter.com, but hadn't changed the port number, which is why the server change didn't work for me. When I changed the port number from 465 to 587, that did the trick.

Hi - I'm experiencing this too. No settings were changed for years prior to this new error. I did all the suggestions above to no avail. Any other thoughts?

Thanks in advance
