[Dovecot] Plus addressing

It appease that I can enable +address filtering into separate mailboxes by simply setting

$recipient_delimiter = '+';

However, is there anyway to get great control over that?

For example, on one account I have a lot of +addresses I use. A few, I sort into mailboxes (like my bank, credit cards, etc). The rest are either on the “spammer => /dev/null” list or get sorted into a mailbox named “Misc” (like various newsletters and offers and sales from companies I do business with).
