Thunderbird email downloads stopped working

The pop server settings would be for pop.mailspring.com, but the outgoing would use the earthlink smtp smtpauth.earthlink.net. Their website only mentions IMAP for mailspring.

I'm wondering if they are not supporting up to date protocols for mailspring.

Did you update Thunderbird from a version 68* to a 78* version ? If yes: I suggest you try resetting the minimum TLS setting - see info on how to do it here:

• https://support.mozilla.org/en-US/kb/thunderbird-78-faq#w_after-upgrading-to-thunderbird-78-i-cannot-receive-or-send-email-messages

Then restart Thunderbird.

Hi!

I've already tried resetting the minimum TLS setting to 1. This does not fix the issue. Thunderbird still connects but times out without downloading any emails.

Any other suggestions?

Thanks!

Check webmail for a corrupted message:

This does not fix the problem. I've deleted everything in webmail. Thunderbird still connects but times out without downloading anything.

Timeouts can be caused by the antivirus app if it's incompatible with TB and the TB profile folder isn't excluded from scanning (which doesn't affect the real-time background scan). Adjust your AV settings or test TB with Windows running in safe mode.

Tested this. No change. I'm running Norton 360 and TB is configured in it. I've been running this setup for several years with no problems. This issue started when the newest update (78.10.2) to TB installed on the 19th of this month.

re :I'm running Norton 360 and TB is configured in it.

I have had a few reports that involved Norton 360 after last update and the following fixed the issue, so please try this.

It is possible that Norton got confused by the Thunderbird update and thinks it is a different program or one part has not got set up correctly so a port is being blocked. Try this first.

• Exit Thunderbird - this is necessary.
• Start computer as normal.
• Access Norton
• Under 'Settings' > 'Firewall' > 'Program Control'
• scroll down until you locate C:\Program Files (x86)\Mozilla Thunderbird\thunderbird.exe

It should say 'Allow', but select 'Custom' from drop down option. A new window opens: Does it say exactly the following: * Thunderbird, Allow, Direction: In/Out, Computer: Any, Communication: Any Protocol: All, And is the checkbox selected with a blue X ?

If no, something is different from the above, eg: Any Protocol does not say 'All'

• click on 'Modify'
• Actions tab - select 'Allow
• Connections tab - select last one -'Connections to and from other computers'
• Computers tab - Select 'Any computer'
• Communications tab - select 'All'
• Advanced tab - select If explicity requested
• Description tab - Type Thunderbird
• click on all the OK's
• Then make sure it says 'Allow'

If it says all of that already: See if the following forces a resync - select 'Block' and click on Apply and then cick on 'Close' and exit Norton.

Then access Norton Firewall again, look for Thunderbird as before and select 'Allow', 'Apply' and 'Close'

Now start Thunderbird.

People reported that forcing the resynch got it up and running.

Initially this did not work.

However.....

I set Norton to Block, then rebooted my computer, then reset Norton to Allow.

This worked!

Thanks for everyone's help! :)
