Bon dia, ja ja un temps que el meu proveïdor de correu "Runbox" m'envia
el següent avís: 

...............

We will be retiring support for TLS 1.0 and 1.1 and will only support
TLS 1.2 or later................

Our logs show that an email program you have used in the last month has
connected to our service using an outdated type of encryption we will
no longer be supporting. This means your email program may stop working

No m'aclaro si em falta alguna cosa per instal·lar. També fa un temps
vaig canviar la app del correu del mobil per si era aquesta però l'avís
continua arribant. 

Si algú em pot orientar li agrairé.

Salutacions. Jordi.
