I am trying to install Dovecot for the very first time ever. As far as I see I do have Dovecot up and running already, but I am not happy about these selfsigned certificate that is assigned to.
I am trying to change this with my own corporate wildcard certificate, but it seems I am doing something wrong here. I need some help with this as it is security related and not really a basic installation thingy.
Well, what did I all do?
Inside the /tmp folder I have downloaded the Pfx (certificate including private key) file.
I used openssl to get the files I need:
openssl pkcs12 -in wildcard.pfx -nocerts -out wildcardkey.pem
(here I entered the import and PEM passwords - I now have an encrypted key)
openssl rsa -in wildcardkey.pem -out wildcardserver.key
(here I have the decrypted key)
openssl pkcs12 -in wildcard.pfx -clcerts -nokeys -out wildcardcert.pem openssl pkcs12 -in wildcard.pfx -nodes -nokeys -out wildcardchain.pem
I moved wildcardcert and wildcardchain to: /etc/ssl/certs I moved wildcardkey.pem and wildcardserver.key to /etc/ssl/private
Now I have editted ssl_cert and ssl_key as follow:
ssl_cert = /etc/ssl/certs/wildcardchain.pem ssl_key = /etc/ssl/private/wildcardserver.key
So, what am I doing wrong?
Now I get an error after restarting Dovecot:
lmtp(5935): Error: SSL context initialization failed, disabling SSL: Can't load SSL certificate: There is no valid PEM certificate.
What am I doing wrong?
Because my Postfix looks ok?
smtpd_tls_key_file = /etc/ssl/private/wildcardkey.pem smtpd_tls_cert_file = /etc/ssl/certs/wildcardcert.pem; smtpd_tls_CAfile = /etc/ssl/certs/wildcardchain.pem; smtpd_tls_key_file = /var/lib/nginx/ssl_passwords.txt;
