If I use smtpd_reject_unlisted_recipient=yes or smtpd_recipient_restrictions=reject_unlisted_recipient options all messages to non-existant addresses are rejected. But if anybody sends message to multiple addresses in same domain and one of them doesn't exist then postfix doesn't deliver such messages anywhere.
How to tell postfix to reject mail to non-existant mailboxes only and deliver it to valid recipient? Thanks a lot, Oleksii
