-n: If the destination mailbox doesn't exist, don't create it. This affects both -m parameter and fileinfo action in Sieve scripts. The fallback is to deliver mail to INBOX.

(typo: fileinto not fileinfo)

My testing shows that if the mailbox does not exist then the mail is rejected like so:

=== Your message was automatically rejected by Dovecot Mail Delivery Agent.

The following reason was given: Mailbox doesn't exist: mail-lists.debian

has anyone else used the -n with a non-existent mailbox and had the mail delivered to INBOX like the wiki states?
