E-mail aliases can be used as temporary disposable addresses that can be published on the Internet. When spam starts coming to an address that was set up as an e-mail alias, you can remove that alias and create another one.
1) Start by going to the mail tab.
2) Click an e-mail address.
3) Select the e-mail aliases tab.
4) Type the alias name.
5) To create a second alias, click the link here.
6) Click ok.
Now any mail sent to firstname.lastname@example.org will automatically be forwarded to email@example.com.
This is the end of the tutorial. Now you know how to create e-mail aliases in Plesk.
