Re: While doing ESRS configuration which email address to give
ESRS Configuration Tab in ESRSVE GW is for notification from ESRSVE to customer and failover dailhome method via SMTP.
You do not have to configure it, it's a option, not mandatory.
SMTP section for Unity array seems to be for Emailhome.
I do not know well about the latest version of Unity but in past Unity can configure only either of both ESRS dialhome and Emailhome.
If you want to configure Emailhome other than ESRSVE dialhome via RESTAPI, you can set either customer supplied SMTP server or ESRSVE IP address.
But most commonly, it should be the customer supplied SMTP server IP because if it is ESRSVE IP you should use to RESTAPI method to dialhome from Unity.
