View source for Email alerts failing to send from Dell iDRAC v9

If you have a Dell server with an iDRAC9, 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.'' 

The tell-tale sign of this is when you see the following message in your mail server logs:

  Dec 10 00:33:28 mailhost01 sendmail[22446]: 1BA0XSsj022446: idrac.mydomain.com [192.168.2.2] did not issue MAIL/EXPN/VRFY/ETRN during connection to Daemon0

To start receiving email messages again, disable the email encryption by using the following RACADM command:

  racadm set idrac.RemoteHosts.ConnectionEncryption None

As of iDRAC9 release 5.x, you can change this from the GUI:

  - iDRAC Settings
    -> Settings
       - SMTP (Email) Server Settings 
         -> Connection Encryption : '''None'''
