Stopped sending emails
I have been using Mozilla Thunderbird for decades and they have even contributed a small amount of money to Thunderbird periodically. Just within the last two or three days all of a sudden I have been unable to send emails with my phone. I receive emails, but I do not send them. So I opened up a laptop where I did not have Thunderbird and set it up properly through Spectrum using the incoming and outgoing servers as mail.twc.com. and yes, just like on my phone. I continue to receive new emails, but even with the laptop I was unable to send an email. I received the message"send message error sending a message failed. The message could not be sent because the connection to outgoing server smtp mail.twc.com was lost in the middle of the transaction. Try again."I contacted Spectrum twice and both times they had me try to send a message through their Web server spectrum.net and that message did go through. Of course then their response is that this has to be a problem with the third-party app meaning Mozilla Thunderbird, and they can’t help with that at all. I sure would appreciate some help because I hate to walk away from Thunderbird as well as change my email address after all of these decades.

I am not an expert with Spectrum, and they regularly deny all responsibility, as I see users posting regularly here with the same complaint. This info may help, but there are many varieties (I think) in Spectrum accounts:
https://www.spectrum.net/support/internet/email-settings/
incoming IMAP: mail.twc.com, 993, SSL/TLS, normal password, email address
outgoing SMTP: mail.twc.com, 587, STARTTLS, normal password, email address
thank you for your reply. Unfortunately, that doesn’t solve it because those are the settings I use and have been using. It’s only in the last two days. It stopped sending emails.
Did you start using a VPN or receive an update to the antivirus or VPN? The fact it also doesn't work on the phone suggests it's a Spectrum issue.
No VPN. I cannot send out on the phone or on my laptop. I can send out On Spectrum's Webmail. Thus they say it is not their issue.
If you can send from the phone through the cellular network, it might point to the modem/router (try restarting it). Webmail sending and SMTP are separate processes, so their claim is a red herring.
If I’m understanding you correctly about sending it via cellular data, I turned off my Wi-Fi and tried to send a message that was in my outbox, and it immediately went to the top of my outbox meaning and that it didn’t matter if Wi-Fi was on or not.
1. What app are you using on your phone? 2. Is your email address one of the legacy roadrunner ones? perhaps one that uses brighthouse servers
Are you using the spectrum service to connect to the internet? I have seen several issues of late where the problem is spectrum refuse to send mail unless you connect using an IP address they consider they issued. SO a VPN will automatically fail. Non spectrum hotspots will fail as will wifi in hotels and motels unless you luck out by being in a business that shares a provider with you. One chap was in Houston on business, suddenly he could not send mail.
Given the skills I am seeing of late from Spectum it is entirely possible they have blocked a larger swathe of their own users from sending mail via their own SMTP server because they have a skills issue. They do not apply the sending restriction to their webmail, only to sending via their SMTP server.

3. Is your ISP given as Spectrum? 4. What is the IPV4 address given at that website?
