My users are constantly asking when Kerio will support Address Tags (also known as 'plus addressing').

You can setup <username>-* as an alias that points at a user which then acts as a wildcard to simulate this behavior. Im not sure how there handled by the client (for rule setup) however.
It's an extra administration step though if you want this to be global.

At our most recent MacTech BootCamp III for Apple consultants, + tags were a good part of the discussion during one of the sessions (Apple IDs). The general consensus was for people to use it on Google hosted domains, but there were specific comments about not being able to use it on Kerio.
Please add this support.
