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?

can you try this to get rawlogs to find out what happens?

I'm bit confused, how this rawlog works. I did:
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 .
drwxr-xr-x   12 root     root         4096 Dec 12 12:41 ..
drwx------    2 kaka     kaka         4096 Dec 12 12:41 dovecot.rawlog
drwx------    2 kaka     kaka         4096 Dec 12 12:41 Maildir
Added into dovecot.conf:
protocol imap {
rawlog_dir = /tmp/rawlog/%u
}
service imap {
executable = imap postlogin
}
service postlogin {
executable = script-login -d rawlog
unix_listener postlogin {
}
}
But /tmp/rawlog/kaka/ and /home/kaka/dovecot.rawlog/ are empty. What did
I miss?

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