Hi

Your email sent to {{ destination }} from {{ alias }} ({{ subject }}) contains an address which isn't a reverse-alias in the To: or Cc: field.

This will reveal your real mailbox address.

Please create a reverse alias for each recipient to make sure your mailbox stays hidden.

More info about reverse-alias can be found on https://simplelogin.io/docs/getting-started/reverse-alias/
and how to send an email from your alias on https://simplelogin.io/docs/getting-started/send-email/

Please let us know if you have any question.

Best,
SimpleLogin team.
