ServiceDesk Plus host URL

ServiceDesk Plus host URL

We have SD+ working fine from http:\\helpdesk:8080 but wish to present SD+ also on another URL e.g. zzzhelpdesk:8080 ( this is because on a seperate site they already have another entry for "helpdesk" in their DNS) ( and change the notification emails accordingly to come from zzzhelpdesk:8080)
 
I understand there is an URL Alias setting within the Admin, Self serve settings, but will this change the email notification template to the new address?
 
Any help would be appreciated
