Put the following in /etc/postfix/main.cf:
recipient_delimiter = +
cheers,

Just FYI;
If you are using dovecot and postfix is handing off delivery to dovecot
(such as LMTP) you also need to make sure that setting is in the dovecot
config or dovecot will backscatter as unknown user.
How to setup dovecot then? Thank you.
Depending on your setup something of this might be relevant:
<https://doc.dovecot.org/settings/core/#core_setting-lmtp_save_to_detail_mailbox>
<https://doc.dovecot.org/configuration_manual/sieve/examples/#emulating-lmtp-save-to-detail-mailbox-yes>
<https://doc.dovecot.org/configuration_manual/sieve/examples/#plus-addressed-mail-filtering>
But that's a topic for the dovecot list.
