I've followed godaddy's instructions for applying the godaddy cert to courier-imap
here are their instructions:
I also tried TLS_TRUSTCERTS=/etc/ssl/private/gdca.txt as I have found instructions that state that.
I'm not sure what's wrong but I can't connect to port 993 since I moved from self-signed to CA signed.
Did I miss any other settings in imapd-ssl config?
