Couple of things you might look at. First, I think you need to drop the
-des3 option when you create the private key. Do something like:
openssl genrsa -out xxx.key 2048 instead. Otherwise, you wind up with an
encrypted private key that needs a pass phrase every time you start the
server. I didn't think Cyrus would even start with a key like this.
Apache is about the only thing I've used that would prompt you for a
pass phrase on start up.
To remove the key pass phrase you can do something like:
openssl rsa -in xxx.key -out xxx.key.nopass
I haven't used GoDaddy certs for a while because you had the extra
hassle of dealing with intermediate certificates, and I can get
single-root certs cheaper. That being said, I believe all you should
need to do is cat the signed cert and the intermediate cert together,
and use this for the tls_cert_file: value in imapd.conf. Point the
tls_key_file: value to your private key, and that should do it.
This is all off the top of my head and a sick child meant I only got
about 3 hours of sleep last night, so please make copies of everything
before trying any of this!
