Keep your company email working. Authex Labs manages the controls behind company email for small businesses: which services can send as the business, and which people and applications can access its email platform. Authex Labs maintains supported SPF, DMARC, MTA-STS, TLS-RPT and BIMI controls on delegated domains. DKIM signing stays with the sending provider. Read-only Microsoft 365 reviews cover supported access and security settings within granted permissions and licence limits. Supported changes require customer authority and verification, with recorded evidence and human help for exceptions. Authex Labs does not read email content. Authex Labs is a brand of Hemanth Vishnu Advisory, an Indian sole proprietorship owned by Akula Hemanth Vishnu. New signups are paused. Existing customers continue under their agreed arrangements.
