Dovecot 2.2.27 & windows 10 outlook (no auth attempts in 0 secs) error.

Edit: When using win8, then logs started appear in dovecot.rawlog. But
as win10 gives error in ssl level, before user authentication, then no
debug logs will be written into user dovecot.rawlog folder.

So how to debug this ssl issue?

doveadm user -u kaka
userdb: kaka
  user      : kaka
  system_groups_user: kaka
  uid       : 566
  gid       : 566
  home      : /home/kaka

ls -al /home/kaka
total 16
drwx------    4 kaka     kaka         4096 Dec 12 15:36 .

Added into dovecot.conf:

service imap {
  executable = imap postlogin
}

service postlogin {

I miss?

This sounds like issue with SSL itself. Is your certificate self-signed 
or issued by some trusted CA?

Also, Outlook doesn't allow storage of a certificate like Thunderbird 
but it does allow you to accept it (every time one opens Outlook) and open.
