What is an email alias and what is it for? (Windows Hosting)
An email alias is an alternative address you can give to an existing e-mail address or group of addresses.
In practice, if you create an alias called info associated with one or more email addresses, for example, Paul@yourdomain.com and Bob@yourdomain.com, all the messages sent to “info@yourdomain.com” will also be received by both Paul and Bob, but the ”info” address doesn’t exist as a mailbox in its own right, so you cannot configure your e-mail client to log into it, or access it through webmail.
