Mail aliases are email addresses that simply forward email to the mail box that contains the alias. If you would like to set up an alias for one of your mailboxes:
• Log into your Plesk through your customer manager
• Once you log into Plesk , click on the “Mail” icon
• Select the mail box you would like to create the alias for by clicking on the email address
• Click on the “Add New Mail Alias” button
• Enter in the alias name and click “Ok”
All email sent to the alias will arrive in the parent email’s inbox.
