New support for sub-domain addressing

Description

All forwarders of subscriber accounts now support a target address of the form "slug@keyword.domain" - where before you could send an email to "slug-keyword@domain", you can now also send an email to "slug@keyword.domain".

Details

The new "sub-domain" addressing scheme doesn't require you to create new forwarders, it's just considered an alternate way of sending mail to the same forwarder, which means:

  • blocking email on the "keyword@domain" forwarder blocks both styles of addressing
  • emails to either styles of address are published on the same endpoint if RSS addressing is enabled
