Authorisation Process when using GeoTrust.
Geotrust will only send the authorisation email to firstname.lastname@example.org.
Whichever email address you request as the reply address for your GeoTrust SSL Certificate they will ony send the authorisation email to "admin".
If you do not have such an email address you should create one; if Ozhosting is hosting your email this can be done as an alias of your own email account and there will be no charge for that. Just log in to your Control Panel and go to Billing, then to your Exchange management tab and add an additional mailbox.
