RAC0225: Sending the test mail failed troubleshooting
Integrated Dell Remote Access Controller 9 (iDRAC) SMTP test mail fail, error message:RAC0225: Sending the test mail failed.
Check mail relay server log (sendmail):
[iDRAC IP] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
Solved:
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
