I have a domain on a hosting account. I intend to create a subdomain, which is easily accessible by my domain. The subdomain will be mail.mydomain.com. I'll install an email php script on subdomain mail.mydomain.com. When users create accounts at mail.mydomain.com, will their email addresses show: email@example.com or firstname.lastname@example.org ??? I, of course, would like for their email addresses to be email@example.com, for simplicity purposes.
