Forum d’assistance Thunderbird

My wife & I have the same PCs running Windows 10 & Thunderbird 115.11.0 (32bit).

We have a hosted web-site that also supports email, and we each have an email account (eg neddy@goon.com.au & minnie@goon.com.au). I've checked that both our POP server configurations are identical but despite that about once a week minnie@goon.com.au receives a warning to add security exception but neddy doesn't. This started happening two weeks ago after a years error free running.

The host has checked that goon.com.au has a valid SSL certificate, so what could be causing the discrepancy and how do I set about fixing it please?

Some mails always end in spam folder no matter which settings I have tried for example collected adresses or check/uncheck spam settings. For a test I have two hotmail accounts. When I from thunderbird send mail from one to the other, it ends in spamfolder. But if I from the same mail account from outlook.live website send mail to the same account, it doesn't end in Thunderbird spam folder. Besides this many other safe and regocnized mailaccounts recently starts to end in spamfolder. Can any thing be done?

Hi, I´ve some Outlook accounts with two step verification login. Anytime I open Thunderbird I´ve to verify myself by selecting a number on my mobile. Is it possible that Thunderbird get´s directly to my outlook account without that veryfying process? Thanks for answering.

Our app sends an email advising the specified individual to note a series of images presented in three rows of nine. The rows display in Gmail via Windows->Chrome, via Android, and iOS with a Yahoo account.

But not in Thunderbird. This is a serious issue as I believe I have followed all the correct settings including in-line display, and yet for some reason, Thunderbird does not display the images.

Any suggestions are appreciated as I am baffled since Thunderbird has been my go-to email client for years.
