My E-Mail provider sent me an E-Mail some weeks ago that TLS 1.0 and TLS 1.1 is no more supported in the future. Since yesterday, I cannot receive mails anymore with the current pmMail 3.24 version. Sending E-Mails is still working.
I get the very helpful account error message
Error: Error 0
I do not find any content about TLS in the pmMail documentation.
The more detailed query in english language is here:

Stunnel, which is provided with PMMail, supports TLSv1.3 tunneling. Look for the readme in your \PMMail\BIN\Stunnel directory. Would TLSv1.3 work with your provider?

Thank you for your hints. I added the following to my stunne.conf:
;TLS Version (Strato since 7/2021)
sslVersion = TLSv1.2
The first trial failed, because in the General Settings of pmMail 3.24, page Secure Transfer, there was still an old stunnel.exe version selected.
Then I realized that if no sslVersion switch is selected, the new stunnel.exe version also works. It seems that it select TLS 1.2 as default.
