Not Able To Send Email to Hilton.com

Recently Hilton.com made security changes to their email, preventing some domains from being able to send to it. This is a security improvement, but does have consequences for misconfigured email senders. This is likely a misconfiguration of your email. CSSI can work with you to configure your email so it can send to Hilton.com. Give us a call at 869-226-9222 to discuss an email audit for your email.
