Sender authentication is a critical technology that will help solve several of acute problems with email today, including fraud, spam and false positives. Since email authentication standards tend to change frequently, Port25 Solutions, has been at the forefront providing insight as a technology vendor to determine its effectiveness at combating spam.
Port25’s leadership role has helped make sender authentication a reality by actively participating in the standards development efforts and by being first with product offerings that help make it easy for legitimate senders to adopt email authentication.
To ensure maximum delivery and to help separate legitimate email from spam, senders have realized that adopting these updated authentication specifications increase message validity and does play a part in determining inbox placement.
The challenge is that specifications can be complex, and there are several competing standards that are subject to change and different receivers will prefer alternative methods of authentication. PowerMTA’s DKIM Wizard authentication tools make it easy for senders to adopt the latest specifications and ensure on-going compliance.
