I installed roundcubemail.
I can receive and send email.
The wordpress problem.
The email from the wordpres link to change email and change password also arrives.
It was not possible to install on ports 587 and 993.
I followed this German tutorial.
In 17 minutes of the video, his problems were mine.
He also failed and had to change the doors.
Only IMPA was he able to change port 143 to 993.
and use ss: //host.example.com.
I was unable to use the certificate.
The problem with you is that of the certificate. But which one should I use as a default?
