Why do I have to use my amateur radio callsign as my alias?
Amateur radio callsigns are globally unique and recognized world-wide. By restricting mail aliases to valid callsigns, we avoid any arguments over who gets to be “bob@amsat.org”. Besides, other identifiers don’t meet the primary purpose of the mail alias service, which is to help radio amateurs find each other by email. We have made exceptions for amateur radio organizations with world-wide recognition, and for certain special functions of AMSAT-NA.
