When configuring a custom email domain, the email domain set up wizard only allows you to select a pre-determined email domain, which consists of "smartsheet".+(primary email domain) or "smartsheetmail".+(primary email domain). Per enterprise email policy at Johns Hopkins, automated emails sent from associated vendors may not be sent on behalf of our primary domain. Subdomains are created and follow the format of mailXXX.jh.edu which are to be used by the vendor.
Enhancement Request: Allow for custom entry of subdomains in the custom email domain configuration wizard, preventing the need to use "smartsheet" or "smartsheet" mail followed by the domain.
