Can't configure mail account

Hi

My web host just changed his server and now I cannot reconfig my mail accounts to this new server securely.

The server name and passwords are correct, but when I manually set my incoming mail port to 993, and outgoing to 465, and select "SSL/TLS" in the SSL drop-down menu, I just get the error message, "Thunderbird failed to find the settings for your email account". The only way I can get my email accounts to send/receive emails is to set SSL to "None", but I believe that is insecure?

During the mele of problems I have encountered, I deleted my BT Internet Premium email account from Thunderbird and whenever I try to set that up, I get the exact same issue. Needless to say, BT's support staff were absolutely useless!

My OS is Windows Home 2004, Thunderbird 78.51, and I use ESET Smart Security Premium 14.0.22.0

Any suggestions please?

Thank you.

please disable your AV (ESET) "mail-protection" option, more info.

if that doesn't solve, please goto your mail service provider's MSP's or ISP's web-access site, find the option to generate secure-mail-key (they may use a different word/words), create a new key/code, remove saved password from inside the TB, & use that new key/code (from your MSP's site) in TB, in the place of "password" field/box. select "normal password" authentication-method / auth-method, & secure "SSL/TLS". and restart TB, try again.

as you've tried NONE (means: no encryption security) , your password is exposed , change your MSP/ISP web-access password.

you may see more info on related matters, here.

There are two possibilities. The problem you are experiencing could be either of the following or a combination of both.

1. There have been a lot of reports about ESET/NOD32 If you are using ESET/NOD32 security/AV then probability is very high it is causing your problems. According to their forums, you should temporarily disable SSL until they solve the problem per https://support.eset.com/en/kb3126-disable-ssl-filtering-in-eset-windows-products?ref=esf - the problem is being reported by dozens of users https://forum.eset.com/topic/26517-problems-with-thunderbird-and-imaps/ https://forum.eset.com/discover/

2. If you are using version 78* Thunderbird has set a higher minimum value for TLS. If the server you use is still using older TLSv1.0 or TLSv1.1 then you need to lower the minimum settings in Thunderbird. This is what you need to do in Thunderbird to reset the minimum setting.

  • In Menu app icon > Options > General
  • Scroll forever to the bottom and click on 'Config Editor'
  • accept the risk
  • In search type: tls.version
  • look for this line : security.tls.version.min
  • Double click on line to open an edit window and enter the number 1
  • click on OK.
  • Exit window - top right x

This will set that preference back to the same level as used automatically in version 68*.

  • Exit and restart Thunderbird.
