Hello Stephan,
Maybe this is not an issue at all and nothing but a curiosity; maybe though you do care:
When there is only a local part in "To", the "subaddress" extension does not match on the "detail" part.
This happened when I made a device on the LAN send to "name+foo", where "name" is a system account on the computer used as smtp.
Such mail gets filed into INBOX. Matching the whole address against "name+foo" works. This is with dovecot-sieve 2.2.13, postfix here obviously does not alter the To header.
