SMTP Server settings do not appear to accept underscores - PI-008149

FYI - PI-008149

The SMTP Server settings do not appear to work if the email address contains an underscore, or any special characters I suspect.

I was trying to test this config with svc_jamf@domain.com and would continue to get the same error message in the Jamf server logs.

javax.mail.AuthenticationFailedException: 535-5.7.8 Username and Password not accepted. Learn more at 535 5.7.8

The support article noted there suggests enabling "Less secure app mode" on the account itself, which was done.

I managed to successfully configure the SMTP Server settings up by using svc.jamf@domain.com instead.
