However, under Linux the ipop, imap, etc certificates are in /usr/share/ssl/certs and the https certificate is in a completely different place.
The place certificate is on the disk, and the name of the file (or extension on the filename) is not important. For each and every application you mentioned, you can change where it searches for the certificate from the application's configuration file (for example, /etc/httpd/conf.d/ssl.conf for Apache web server). So you can point all of them to look for certificate in /usr/share/ssl/certs, or /etc/certs, or wherever else you choose to store it on the disk. They can all share the same file.
If you don't want to change default configuration (don't see any reason why you wouldn't want to do it, but that is your call), just create symbolic links or make copy of the files wherever the application expects the certificate to be.
