Hi {{name}} We have recorded an attempt to send an email from your alias {{ alias.email }} using {{ sender }}. Please note that sending from this alias only works from alias's owning mailboxes, that are {{ mailbox_emails|join(", ") }} This is to protect against "email spoofing", i.e. someone else sending emails from your mailbox. If {{ sender }} can indeed send emails from your alias, you can add it to the allow list on {{authorize_address_link}} If you think this is a wrong alert, please let us know by replying to this email. Best, SimpleLogin team.
