Hi list,

I have installed dovecot-- and
on RockyLinux 8

Since last update on Microsoft my clients cannot send emails.

In the log I dont see any error,
on the client:
Task "myuser at ... - Sending: reported error (Ox800CCC1A) :
'Your server does not support the connection encryption type you have
specified. Try changing the encryption method. Contact your mail server
administrator or internet service provider (ISP) for additional assistance.'

Do you have any advice how I could change the server settings?

best regards
