iDRAC 9 enterprise SMTP configuration

Hi,

I'm struggling with the SMTP configuration. I keep getting the RAC0225 error (unable to send test email).

 

My settings :

- A few alerts are ticked

- Two emails addresses are setup and activated

- SMTP server IP address

- Personalized sender address (I've tried with the default too)

- SMTP port 25

- No auth needed

In the common network settings :

- DNS registration is enabled (I've tried disabled too)

- DNS name is setup "iDRAC-SRVREPLICA"

- Automatic domain name configuration can't be changed

- Domain is setup. The same as our WIndows domain. (I've tried our email domain too)

- Registration time interval 0 seconds

- Connexion vue enabled

- Both LLDP options disabled

- The iDRAC has an IP, a gateway, a netmask and two DNS servers from the domain

 

Tests I've done :

- ping the smtp server from the racadm

- ping both DNS servers from the racadm

- send to another email address (gmail)

- Reset the iDRAC

- "testemail" from racadm, same result

 

SMTP server side :

I see a "EHLO" immediately followed by a "QUIT" (Windows server 2019).

 

Configuration :

- DELL PowerEdge R540

- ESXi 6.7 U3

- iDRAC version 4.22.00.00 (july 20)

 

What's strange is that there is an iDRAC 8 server with basically the same configuration and it's working just fine.

Any idea ?

Thanks
