SMTP logon fails starting 8/16/19

Размещено

SMTP (email upload server) logon to Suddenlink.net started failing 8/16/19. Emails can not be sent

POP (download email server) works just fine.

Emails can be sent and received via Suddenlink website and the problem only occurs while trying to use Thunderbird

Ping of smtp.suddenlink.net by name and by IP Address (208.180.40.68) works just fine.

Internet connection works just fine

The problem is that Suddenlink has removed legacy SMTP access via port 587. Suddenlink Tech Support was not aware of the change.

Solution is to change Thunderbird SMTP configuration. highlight the email account - click on "View Settings for this Account" - Edit SMTP Server.

Change the Connection Security to SSL/TSL Change port to 465 Change Authentication Method to Normal Password

Click on Ok and retry. I did not have to end and restart Thunderbird

Hello Josef46,

Just to verify, Thunderbird has been working, you're email is suddenlink.net and yesterday Thunderbird stopped sending emails. Thunderbird can receive emails without errors. Sending emails fails with a SMTP logon failure. And ping smtp.suddenlink.net runs without error (if using Windows cmd.exe will give a c: prompt so that you can type in "ping smtp.suddenlink.net"

If that's accurate, what are the the port, connection security and authentication values in the SMTP server configuration.

I have tried this 4 times. Always says smtp times out and send failed. the setting is SSL/TLS not SSL/TSL on mine.

Hello,

You are correct, I mistyped. The correct selection is SSL/TLS.

Can you long on to your Suddenlink.net ID via web brower? Go to www.suddenlink.net, click on email and logon with your Suddenlink ID (suddenlink email address without the @suddenlink.net) and the password that Thunderbird knows.

Password in Thunderbird is found via Tools - Options - Security - Passwords - saved passwords. While you're there compare the passwords for mailbox://pop.suddenlink.net and smtp://smtp.suddenlink.net. They should be the same and match the password that you just used to log onto www.suddenlink.net via the browser.

This will verify that your suddenlink account is good and that Thunderbird is using the correct passwords.

Thank you @Jackb.luddite. Your solution worked for me.

I just spent about an hour on the phone going through menus and talking to incompetent tech support. One person said that it must be a server problem because she could not connect to the smtp server with her browser. On my second try, I finally got a tech that reset my passwords but of course that didn't work.

Thanks again.
