Why are scheduled Splunk dashboard emails not delivering to group email ID?

[rbabu]

While scheduling Splunk dashboard, mails are not delivered to group distribution email id but are getting delivered to individual email id (if given).
I scheduled my dashboard to following emails: dev-gbroker@xyz.com, abc@xyz.com, lmn@xyz.com. Mails are delivering for abc@xyz.com, lmn@xyz.com but not for dev-gbroker@xyz.com.

Please advise

Cheers,
Ramesh

A lot of times, group email aliases require authentication in the email server. For example, in the company I'm working for as a consultant I can't email group aliases (they're running exchange) from my outside email address, I have to use my internal email address to access those group aliases. I imagine something similar is occurring here - perhaps check with your email admins?
