In order to get callhome email alerts, use the nas_emailuser functionality. This will send the same alerts as call home, using sendmail from the controlstation. nas_emailuser will send unencrypted and human readable emails.  Do not add non EMC email addresses to the call home emails.
I am trying to setup event notifcation emails for block storage for all alert events.  When a test email is sent, it comes with an attachment with .xml.en2 extension.  We also have EMC call home enabled.  My understanding is with call home enabled the alert notification are all encrypted (the .en2 extension?).  Is there any way to receive readable email alerts while still having the call home enabled?
vnx/unisphwere email alerts with call home enabled?
