[qmailtoaster] Outlook users get "unsupported encryption type" error after Windows update

[Andreas]

Hi list,

I have read the discussion and fix.
I have installed dovecot--2.3.19.1-2.x86_64 and
dovecot-mysql-2.3.19.1-2.x86_64
on RockyLinux 8

Since last update on Microsoft and Outlook they cannot send emails.

In the log I dont see any error, on the client:
Task "myuser@... - 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?

Andreas
