## POST /api/v2/me/mail-relay/blocks/unblock

**Lift a paused mail relay sender**

Lifts a pause the outbound mail relay put on one of your senders. Take `blockScope` and `blockValue` from `scope` and `value` of an entry in `GET /api/v2/me/mail-relay/blocks`. The relay still checks every message afterwards. A sender that keeps sending the same kind of mail is paused again, for longer. When the entry has `passwordChangeAcknowledgementRequired: true`, change the mailbox password first and send `passwordChangeAcknowledged: true`. You can lift a pause on the same sender 3 times in 7 days. The pause ends within a minute. Until then the entry shows `unblockPending: true`.
