and AOL implemented a change to their email system respective to the DMARC policy. DMARC, which stands for Domain-based Message Authentication Reporting & Conformance, is an email authentication record that aims to prevent spoofing of the "from" address on messages.

The change in this policy implemented by Yahoo and AOL means that any email message using a "from" address of or (in the message headers) must originate from Yahoo's or AOL's own mail servers. Messages sent through ACTIVE Works® Endurance, Camp & Class Manager, or other ACTIVE Network applications (outside of Yahoo) will be rejected by any mailbox provider that has implemented DMARC. This includes almost all major mailbox providers such as AOL, Yahoo, Comcast, GMail, Outlook, etc.

To prevent future email messages from being rejected, please update your account to a different email address (other than Yahoo and AOL). Please refer to the instructions below to update the username/email address on your account.
