How can I create email alias in ISPConfig for example, I create the user web1_site1 The user has a site. I want to create a set of emails that are alias for the user webmaster@site1.com admin@site1.com sales@site1.com info@site1.com postmaster@site1.com they all point to the user web1_site1. I can do it by editing mail file virtualusertable but need to do it through ISPConfig. Thanks in advance.
