Hi!

Yes, I have "lmtp_save_to_detail_mailbox = yes" and recipient_delimiter set to +. Everything is working as long as I send a message to "user+detail", i.e. to an existing user. The problems start when I try to send to a combination of an alias and a detail: "alias+detail". Then the message is just put into INBOX of the respective user regardless of what I try to define in sieves with ":detail" rule.
