Email alerts failing to send from Dell iDRAC v9
If you have a Dell server with a version 9 iDRAC, release 4.x, you'll no doubt no longer be receiving email from it. The reason for this is:
After iDRAC is upgraded to version 4.00.00.00, you may stop receiving encrypted email alerts from iDRAC, if the external email server does not support encryption. iDRAC firmware version 4.00.00.00 introduces a user-selectable encryption option and the default protocol is StartTLS.
To start receiving email messages again, disable the email encryption by using the following RACADM command:
racadm set idrac.RemoteHosts.ConnectionEncryption None
