to ensure things are working, change this to "no", if you can get mail
then, change it to "yes", dont absolute force until you have everything

How did you generate this? is it really self signed, or is it a CA
signed (you can get free certs)

If it's CA signed, ensure you created it like this (the order *is*
cat mail.crt sub.crt  ca.crt > dovecot.pem

*remove ssl_ca =  ....stuff*
ssl_cert_file = </path/to/dovecot.pem
ssl_key_file = </path/to/mail/mail.key

Been loooong time since I use self signed, but from memory

openssl req -x509 -days 999 -nodes -newkey rsa:2048 -keyout domain.key
-out domain.crt
(and IIRC tou need to ssl_ca = stuff)
dovecot wiki should have the correct format for self signed
