Smtp funktioniert nicht

seit heute funktioniert smtp (emailversand) nicht mehr. Ob 25, 465, 587…, nichts funktioniert. Mein Provider (ionos) hat auf Verschlüsselung TLS 1.2 geändert. Kann emclient das nicht verarbeiten??

A working SMTP using IONOS:


I tried this also, no function.

Do you have Windows 7 ?

yes., its windows 7.
but, btw, thunderbird works without any problems

Have you done the following TLS 1.2 mod in Win 7 . If you haven’t, you need to as is not enabled by default in Win 7. Reboot after doing that too.


thanks :slight_smile: I will do that.
