Cannot send email using Thunderbird anymore. What changed?

So I get this error every time I try to send an email using thunderbird on my laptop:
"An error occurred while sending mail: The mail server sent an incorrect greeting: p-impout004.msg.pkvw.co.charter.net cmsmtp 205.185.222.208 blocked AUP#CMBL."
So for no reason that I can think of, the hand shaking to the Spectrtum POP server messed up. I spent hours on the phone yesterday and when they couldn't fix it, I was told "dont worry, someone will work on this and get back to you".
After some research into this issue this morning, I find out there is a history of issues with the POP servers.
Can anybody resolve this issue? What should I do?
BTW, I can send emails using my phone. I can send emails from the webmail. I cannot send emails using TB on my account or my wife's account. All the settings are correct.
Thank-you

Just recently got a new Win 10 machine and intalled the latest version of Thunderbird (68.3.1). Set up my main @WI.rr.com email and two other @WI.rr.com accounts using IMAP. Seems like my Mail client is not consistantly pulling the email from the server (syncing). Two of the three accounts are working mostly but the one I use the most is the worst. I will see email on the webmail page, but no amount of 'get mail' commands from my client bring the mail to my clients inbox. Often, I will get mail on my client that is two or three days old.
I have deleted and recreated the account on Thunderbird, but the problem continues.
Really strange that if I shut down and restart Thunderbird, all the emails on the server are pulled into my inbox. If I change my password security from none to SSL/TLS, the email will sync. If I change it from SSL.TLS to none and there is email on the server, Thunderbird will sync.
It's almost as if the server is not recognizing the request from Thunderbird or Thunderbird is not sending a request.
I'm using -
IMAP Server: mail.twc.com:993
SMTP Server: mail.twc.com:587
SSL/TLS
Normal password
Then there is this:
See anything strange?
The port numbers are correct.
The servers need to be updated:
I'll give that a try.
Can't log in to that server. It will not accept my username/PW.
Also tried
imap.spectruminc.com:143
sslmail.spectruminc.com:993
and neither work.
Only server address that allows me to access my account is mail.twc.com, and that seems to be intermittant/inconsistant.
Did you also enable SSL?
"Connection Security" is set to SSL/TLS
"Authentication method" set to Normal Password
I don't see anything else in the setup that makes any reference to 'SSL'.
Thanks. Are you able to complete set up on a different device or different email client?
Was just going to report on that. Right now I have 5 unread messages on the server as reported by Webmail. Only 4 of those messages made it to Thunderbird on the new Win 10 machine. All the messages made it to two other clients:
Not working - Thunderbird (68.4.1) on a new Windows 10 home Dell
imap: mail.twc.com:993
SSL/TLS, normal password
All messages made it to: Windows native 'Mail' app on the new Win 10 machine
It auto set up, and is set as
Currently syncing: every 2 hours
Incoming email server: mail.twc.com:993:1
Requires SSL for incoming email
All messages made it to: Email app on my Samsung S7 Android phone
Auto set up
Syncs ever 15 minutes
imap server: mail.twc.com
Security type: None
Port: 143
Sure begining to sound like a Thunderbird problem. But what could cause it to sync some messages but not all? ...and for the reticent messages to sync if I shut down then restart Thunderbird.
I'm also having issues using Thunderbird with Spectrum mail servers. In my case, I'm on the mail.twc.com server, and I am using IMAP. My problem involes getting new messages. Thunderbird isn't properly syncing with the Spectrum servers.
After working on it here, and then taking it to the Mozilla Thunderbird forum, I'm begining to think there are some major compatability issues between Thunderbird and the way the Spectrum servers are configured.
Perhaps someone from Spectrum can chime in here.
It has got to be some incompatibility between Thunderbird and the mail.twc.com servers. I installed a fresh copy of Thunderbird on a different Windows 10 machine that had never had Thunderbird installed - so it was definitely a clean install. Same symptoms, but they sync and don't sync different messages. How do I get someone to look into this?
Moving this to a different path.......
I recently moved from a Win 7 machine to a Win 10 machine. In setting up Thunderbird on the new machine, I decided to use IMAP instead of the POP3 I was using on the old machine.
Thunderbird auto-setup wants to use the server mobile.charter.net, which is the same server recommended by a Spectrum spokesman. However, with an @WI.rr.com email address, mobile.charter.net does not recognize me and I can't log on to that email server. For many years, I have been using mail.twc.com, and that server still allows me to log on. However, I suspect that legacy server is not being maintained properly, and it is creating a problem for me trying to use IMAP. (Thunderbird is not recognizing all new messages)
How would I go about getting my credentials recognized by mobile.spectrum.net so that I could use that server? I DO NOT WANT TO CHANGE EMAIL ADDRESSES. I've had this email address almost since the inception of TWC and changing it would be quite problematic.
Going on 4 days now and still no email via Thunderbird & Spectrum. Something changed and it wasn't Thunderbird. I was using the TWC address before but tried the mobile.charter.net setting for both incoming and outgoing mail. My mail still will not download from your server and I still cannot write an email. This is the message I get.
An error occurred while sending mail: The mail server sent an incorrect greeting: p-impout001.msg.pkvw.co.charter.net cmsmtp 205.185.222.131 blocked AUP#CMBL.
So, Spectrum guy, can you decypher this error message and get me back running again?
Someone seems to have merged two threads here. My issue is Thunderbird not seeing all the new messages on the server. For example right now there are 19 new messages showing up on the webmail page, but Thunderbird has only loaded 15 of them. Trying to work the issue both here and on the Mozilla Thunderbird forums. TB works everywhere except mail.twc.com, and mail.twc.com seems good with other mail clients (Win10 'Mail' and 'Mail' on my phone). So it seems like a compatability issue. Both TB auto-setup and Spectrum support tell me to use the server "mobile.charter.net", but with the old wi.rr.com email address, that server does not recognize me. The only server that I can log into is mail.twc.com, and I suspect that one is not being maintained well anymore.

Can't help with your problem trader, but I finding out a bit more about mine. There *is* an incompatability between Thunderbird and the Charter imap servers. The Charter imap servers do not properly implement the standards.
[much of this translated by me, and may not be technically correct, but get's the idea across]
Some email programs send a 'redundant' SELECT command on the inbox before doing the FETCH. Thunderbird does not send an extra SELECT command on the inbox if the last selected location was the inbox. The imap server is supposed to remember the last selected. Appearantly the Charter imap server does not, so when Thunderbird tried to get new messages, the server does not know where to look. Rebooting TB causes it to send again the SELECT command and it is able to see all the new message -- until somethin new new shows up.
Anyways, didnt matter. I still get error when connecting that says "unable to log in at server. Probably wrong configuration or username or password
Do you have a [email protected] address? (or maybe other legacy email addresses) Which imap server are you trying to use?
Sounds like Charter is using long obsolete/unsupported email software. Openwave/Openwave Email MX/Unwired Planet/Openwave Messaging/Synchronoss Technologies/Synchronoss messaging/Synchronoss Email Suite/Intermail. From a Thunderbird support expert "I lost track of exactly when the Intermail product was no longer supported but according to one bug report four years ago your ISP was using version 9.0 of the software, and your log file shows they're currently using 9.0.1."
Come on Charter, Update your server to something that is fully RFC3501 compliant.
So I put the same info into my phone email client and it works fine.
When is somebody going to look into this
What email server are you trying to use? Are you using mobile.charter.net? If you have a legacy account, that server will not recognize your credentials. If you have a rr.com account like I do try using mail.twc.com as the email server. Port = 993, security = SSL/TLS, normal password.
Your Spectrum.net Login may or may not be your email and password. They are not always, that depends on how you set that up.
Changing your password for your Spectrum.net will not change your password for your email.
