Use outlook 2003 / winXP / IE7.
In short, you need to set your incoming / outgoing servers to use host#.hostmonster.com (where # is the number of your hostmonster as seen in the cpanel). You then use IE7 to access and install the certificates.
Good graphical process here

You will get errors showing the cert is not trusted until you install the certificate to your computer by following these instructions:
Before we get started, please check that you are using host#.hostmonster.com (where # is the number of your hostmonster as seen in the cpanel) for both the incoming and outgoing mail servers. Also be sure to check that the ports you are using in your settings are correct per the protocol you are using. We will be using those numbers in the following steps.
SSL IMAP = 993
SSL POP3 = 995
SSL SMTP = 465
-Open up Internet Explorer (yes unfortunately this can only be done in
IE to our knowledge)
-If you are using vista, you must right click on IE and run as
administrator.
-Go to the URL https://box#.bluehost.com:993 (or if you are using POP3,
use 995) Don't forget to replace # with your server number.
-If you are using visa/IE7, You will see have to click on "continue to
this website...."
-With the alert box that pops up, click on view certificate. If it does
not automatically pop up, double click the keylock in the lower right
hand corner of your browser.
-If you are using IE7, it doesn't popup. Instead it shows a red box to
the right of the address bar. Click on that and click view certificate.
-Next click on "install certificate"
-Click next on "the certificate import wizard" window -Choose the
option "Place all certificates in the following store"
-Click browse and choose "Trusted Root Certification Authorities"
-Click OK.
-Click next.
-Click Finish.
-Click OK and Yes for any errors you may get.
Now repeat the process for the other port using https://host#.hostmonster.com:465 (Don't forget to replace # with your
server number)
Thank you,
