LETU does not support the use of auto-forwarding setup directly by account holders because of the growing risks presented by auto-forwarding settings if misconfigured, or abused during account compromises.
As an example, email forwarding rules are often established by attackers as a way of preserving covert access to compromised email accounts. Even after the user has re-secured their account by changing their password or adding multi-factor authentication, rules setup during the compromise - if not detected and removed - pose a privacy or security risk.
Emerging data privacy and security standards recommend that organizations assist their users in mitigating this risk by blocking emails that appear to be auto-forwarded from inside the organization to outside addresses. LETU follows this security guidance.
