When you execute SAS code to send an email using the FILENAME EMAIL Access Method, if you do not provide a FROM=, the default
value for FROM= prior to SAS Viya 2024.10 was to use the value of userid@pod.

After SAS Viya 2024.10, if you do not specify a FROM= value on the FILENAME EMAIL statement, the default behavior is
to use the following:

• From the 'email' claim in the OAuth token.
• If there is no map of an email into the claim field in the OAuth token, then the FROM= reverts to the previous default behavior. (userid@pod.)
