Email alerts failing to send from Dell iDRAC v9
From Peter Pap's Technowiki
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
