sendmail -bv <address>: create a what-if report: tell what would happen, but do not actually deliver mail[1]- UNCONFIRMED because I could not find the report in my in-box (which was empty).
sendmail -v <address>: create a what-happened report: deliver mail and report successes and/or failures, including replies from remote SMTP servers[1]- UNCONFIRMED because I could not find the report in my in-box (which was empty).
