Setting up Plus Addressing

Plus addressing (also known as sub-addressing) is a method of supporting dynamic, discardable email addresses for mailboxes. If activated, NoSpamProxy assigns, for example, the company user with the email address john.doe@example.com to the email address john.doe+newsletter@example.com.

WARNING: If your corporate email server does not support plus addressing, NoSpamProxy will not be able to deliver inbound emails that use this feature.

Plus addresses (also called sub addresses) are not counted in the context of licensing, provided plus addressing is activated for the respective domain. This applies both to the licensing of modules and to the licensing of services. Only the underlying email addresses of users for whom plus addresses exist are counted.

How to activate plus addressing

NOTE: If you want to use this function, you must activate it here and on the company's email server, e.g. your Exchange server.

1. Go to Identities > Corporate domains.
2. Double-click the domain you want to edit or highlight it and click Modify.
3. Go to the Plus addressing tab.
4. Check the box Enable plus addressing for this domain.
5. Click Save and close.
