Do I understand this correctly? Are you saying if we add a Binding in IIS (with Server Name Indication Required?) then SmarterMail will parse mail.mydnsname.com and realize mydnsname.com is the SmarterMail domain with custom branding and it takes me to that custom login page?
Basing that off your reply, Matt:
We currently parse the url and match it to a domain and show that domain's login display information.
mail.smartertools.com -> (parsed) -> smartertools.com
mail.somethingelse.org ->(parsed) -> somethingelse.org
Does that also work for any subdomain such as: webmail.mydnsname.com or inbox.mydnsname.com?
I'm on 14.2 and it's not working with IIS Bindings and DNS records functional. Those XML files you mentioned seem to be correct.
Anything else I'm missing?
Thanks
