In the Vault, first open Settings → Security → App & device access, create an Email client password for the device, and copy it when displayed. Choose Email & contacts if you also plan to connect the device’s Contacts app with the same credential; otherwise choose Email only.
Open Settings → Apps → Mail → Mail Accounts → Add Account → Other → Add Mail Account on current iOS and iPadOS versions, then choose IMAP.
- Email and username: your full
[email protected]address - Incoming host:
mail.lightdrive.one, port993, SSL enabled - Outgoing host:
mail.lightdrive.one, port587, TLS enabled - Password: the Email client password created for this device
Use the same Email client password for both incoming and outgoing mail. Your main Vault password and Vault app passwords do not authenticate to email. If the device proposes a different port, edit the advanced server settings and use the values above.
