Manage mailboxes

Mailboxes are the protected recipient addresses of your domains. Manage them under Settings → Mailboxes.

Recipient verification

Per domain you decide how unknown recipients are handled:

• Recipient verification on – only known, active mailboxes are accepted; everything else is rejected. Recommended once your list is complete.
• Auto-create – a mailbox is created automatically on first delivery to a new address.

Notes

• A mailbox address is immutable; you can only toggle it active/inactive.
• The number of mailboxes and domains depends on your plan (see Plans & billing).
