What exactly is the problem?

For what ever reasons I can not add Sky Mail (Yahoo Mail) to Thunderbird. It simply not accepting Thunderbird as it is considered not save enough ?!. I tried everything , I am now using Blue Mail.

Anyway thanks for trying, if found a solution , please let me know,

regards,

Isam

Thunderbird has had support for Yahoo's Oauth2 (modern authentication) for some years now. If you use Yahoo's servers to access your Sky mail, then Thunderbird works just fine. When adding the account in Thunderbird, select Configure manually then use the settings given here https://uk.help.yahoo.com/kb/sky/SLN4075.html

Set Authentication method to OAuth2 and you're good to go.
