There is no such thing as a 'Thunderbird account', but you probably mean you have created a mail account for an existing email address and it has been working in the past but has suddenly stopped with error "Login to server failed" ?

Can you offer more info so we can understand your setup.

1. What OS are you using - Windows 10, Mac, Linux ?
2. What version of Thunderbird are you using ?
3. Are you talking about an Imap or Pop account ?
4. Do you have more than one mail account /email address and does the same problem effect all accounts?
5. Is this a problem with incoming mail or outgoing mail or both ?

Please post the following information:

• Menu icon > Help > More Troubleshooting Information
• Scroll down to 'Mail and News Accounts'
• Copy all the data in that area and paste it into this forum question.
• Tell us the account number and server name which has the problem

Please do not alter anything at the moment so we know the current setup.

Hi

1. Windows 10 2. Version 102.4.2 3. IMAP 4. We just have the 1 email account 5. Both

ID Incoming server Outgoing servers Name Connection security Authentication method Name Connection security Authentication method Default? account1 (imap) mail.bodylabems.com:993 SSL/TLS Normal password mail.bodylabems.com:993 SSL/TLS Normal password true account2 (none) Local Folders None Normal password

Account 1 - Name: mail.bodylabems.com

Please check the account settings The Port for outgoing smtp is wrong - it should be 465 for SSL/TLS I can only assume the server names for outgoing and incoming are correct, but in some cases the outgoing is not always the same as incoming. That info would have been supplied by the company hosting website. I checked out xneelo and they say the outgoing server should be smtp.domain.com https://xneelo.co.za/help-centre/email/email-settings/

account1 IMAP Incoming Server:

• (imap) server name: mail.bodylabems.com
• Port : 993
• Connection Security: SSL/TLS
• Authentication Method: Normal password

SMTP Outgoing server:

• Server Name: mail.bodylabems.com - This may be wrong - use smtp.bodylabems.com
• Port 993 This is wrong. You need port: 465
• Connection Security: SSL/TLS
• Authentication Method: Normal password

Please check your computer Firewall. It mght be part of your Anti-Virus product.

Exit Thunderbird Access Firewall Thunderbird program must be set up as an allowed program otherwise the Firewall will block access to the internet. If Thunderbird already set as allowed, then block/remove it, ok it. Then access Firewall again and set up as an allowed program.

If you have a VPN operating then it is likely the server may not accept login. Often they do not accept because they cannot determine the origin of expected IP address. I have Norton Anti-Virus and discovered they had updated and auto switched on a VPN. Switching it off got things going again.

Start Thunderbird.

Hi we have set everything as it should be, added and removed it from Firewall and it is still giving us the same error, it does not seem to be fixing the problem, is there anything else that we can do or is there any other way that someone will be able to manually assist us.

Please let me know as soon as possible as we are not able to access our business email, nor set it up on another emailing site.

Hosting provider xneelo.co.za instructions for setting up Thunderbird to access mailboxes they host are here.

https://xneelo.co.za/help-centre/email/thunderbird-windows-setup/

You would only set Thunderbird up to use Oauth2 if your mail provider supports it/mandates it (as has been the case with Gmail for a few years, and now Microsoft O365 as of October 2022).

If you think you have TB setup correctly and still can't get that to work, xneelo are probably best placed to help you with that.

Whilst the moderators get around to approving the rest of my post, open your browser and type in your mail server name in the address bar. You will see a webmail icon - which should allow you to directly access your mailbox as a quick workaround.

you say added and removed it from Firewall That implies you do not have Thunderbird listed in the Firewall.

Just for clarity - did you mean the opposite - 'removed and then added it to Firewall' ? Because Thunderbird must be listed in the Firewall.

What Anti-Virus product are you using?

re :Hi we have set everything as it should be Please confirm by posting the same info as before:

• Menu icon > Help > More Troubleshooting Information
• Scroll down to 'Mail and News Accounts'
• Copy all the data in that area and paste it into this forum question.

The info I've managed to locate: https://mxtoolbox.com/emailhealth/bodylabems.com/ it seems to say that for smtp you really are using ' mail.bodylabems.com' which is completely different to their help page! But that is an easy fix. First access has to be gained.

re :as we are not able to access our business email, nor set it up on another emailing site.

Access your webmail account directly using a browser. That will confirm the password is correct.

Did you read all the info at the link i provided ? https://xneelo.co.za/help-centre/email/email-settings/

To use the settings I mentioned - xneelo says "Note: This does require your website DNS records as well as mail.example.com and smtp.example.com to point to our hosting servers. If they don’t, or if your site is not making use of our Let’s Encrypt certificate, please use the hosting server name."

I did a check and it looks like dns etc is set up. https://mxtoolbox.com/emailhealth/bodylabems.com/

I noticed the info did not mention ipv6 Maybe that is causing a problem. Please disable the ipv6 in Thunderbird.

• Menu icon > Settings > General
• Scroll to bottom and click on 'Config Editor'
• Accept the friendly warning.
• In top search type: ipv6
• look for : network.dns.disableIPv6 the default will say 'false'
• click on the 'toggle' icon located to the right and it will change to True

Exit Thunderbird - wait a few moments for background processes to complete. Start Thunderbird. Now try the account and report back on results.

Tried that method as well and it still gives the same issue.

Are you able to access the webmail account directly via a browser?
