IMAP Certificate through GoDaddy:
Run command:
openssl req -new -newkey rsa:2048 -nodes -keyout domain.key -out domain.csr
Submit to GoDaddy domain.csr.
Download from GoDaddy zip file for OTHER server.
The zip file will contain 2 CRT files: something like gd_bundle***.crt and ******.crt
Rename gd_bundle***.crt to just gd_bundle.crt
Rename *****.crt to [domain name].crt
Rename domein.key to ssl.key
Run command:
cat [domain name].crt gd_bundle.crt > imapcert.pem
Now copy the files to the proper directories:
cp -i ssl.key /etc/ssl/private/
cp -i imapcert.pem /etc/ssl/certs/
Edit lines in /etc/dovecot/dovecot.conf accordingly:
ssl_cert = </etc/ssl/certs/imapcert.pem
ssl_key = </etc/ssl/private/ssl.key
Restart dovecot: service dovecot reload
Verify enddate for cert:
openssl s_client -showcerts -connect mail.npc-usa.com:993 | openssl x509 -enddate -noout
