Group emails not forwarded to members
Since upgrading to Yosemite and Server 4 I am no longer receiving any emails sent to my groups, which have emails configured. The following are screenshots of the configuration (I believe it is configured correctly, as it was updated from Server 3):
I do believe emails are getting delivered, as I am not getting any bounce errors when sending from gmail or iCloud to these two addresses. However, I am not getting any notifications for the two members of this group.
Any thoughts what might be going on here or how I might troubleshoot this?
