Some mail servers allow a user to append a tag to their email address in order to create an unlimited number of email addresses that all deliver to the same address. For example, if email@example.com was someone's main address, and your mail server supports address tagging, then your mail server will also accept email sent to firstname.lastname@example.org or email@example.com. The text of "+tag" may be used to apply filtering or to create single-use (aka "disposable") addresses. Where mail servers support this feature, it must also be supported on SpamHero in order to work.
SpamHero has implemented address tagging using three symbols as the delimiter.
These delimiters are: + = - (plus, equals and hyphen)
Note that your mail server must support address tagging in order to use this feature. For more information on what address tagging is, see: http://en.wikipedia.org/wiki/Email_address#Address_tags
