ในการนำ certificate ไปใส่ใน exim.cert จะต้องนำ certificate.crt , ca-bundle , trust-root.ca , ca cert ต่างๆใส่ให้ครบ
โดยสามารถเรียงลำดับได้ดังนี้
-----BEGIN CERTIFICATE-----
content ของ certificate.crt
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
 ca-bundle , ca cert
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
rust-root.ca
-----END CERTIFICATE-----

แล้วทำการ restart service exim , dovecot จะสามารถใช้งานได้ครับผม
