This documentation is written for institutional IT departments.
Because emails are means of authorization and authentication for the CPSolvers mobile app, it is crucial that the sending of emails is free of potential interruptions. This documentation outlines the information needed for IT departments to set up the whitelist.
The emails will always come from an email address that ends with: @clinicalproblemsolving.com
MAIL FROM domain is: appmail.clinicalproblemsolving.com
The emails are signed with DKIM, and an example of the signature is as follows, with the most significant portion highlighted:
