Support "Plus Adressing" #1367

Support "Plus Adressing"

Plus addressing means any email sent to username+whateveryoulike@domain.tld is still delivered to your account. The part of the email address between the "+" and the "@" is ignored for determining which account it belongs to. This allows you to create limitless variations on your email address to give out to different people, sites or mailing lists. FastMail

Does not seem to be RFC'ed anywhere, but broadly supported by mail servers.

Haraka already does support address extensions via the rcpt_to.qmail-deliverable plugin, when qmail is the destination MTA. Ultimately, it's not up to Haraka but instead the recipient validation plugin to determine whether any given address is valid or not.

To further emphasize the point: plus addressing isn't something we need to "support". It just works with Haraka. It's the job of the MDA or storage engine to do the right thing.
