A shared email agent that uses @MailSend and is set to trigger (On Event) on new and modified documents no longer works as the field used in the SendTo argument changed. I changed the formula for the field to refer to a multivalue checkbox field referencing Members in the Domino Directory group. The agent used to work when this field simply referenced the group in the Domino Directory.
I tested this agent on another server that was running Notes mail and the recipients of the email were all internal accounts.
It worked with the new field formula. However, the server this app is running on is only running SMTP mail for external users. Is there any other server settings that I need to look into? (Other than those basic settings for SMTP on the Server Doc basic tab)
