- The sender. The fix is on the sending side: your domain, your server or your list.
- What the server says
5.7.19 RRVS test cannot be completed
What it means
RFC 7293 lets a sender require that a recipient address has had the same owner since a given time. If the receiving system never recorded when the mailbox was created or reassigned, and cannot choose a reasonable substitute date, it cannot run the check and refuses the message with X.7.19. The registry gives it a 5xx reply code. RFC 7293 leaves the next step to the sender: reissue the message without the RRVS requirement, or find another way to reach the person.
Common causes
- The receiving system supports RRVS but has no creation date for this mailbox.
- An old mailbox created before the system recorded such dates.
How to fix it
- 01Decide whether the message is safe to send without the ownership check.
- 02If it is, resend without the RRVS parameter or header field.
- 03If it is not, reach the person through another channel.
