OME 2.0 or OME 2.0.1 Not sending alert emails

Hi All,

I'm running OME 2.0 on a standalone Server 2012 r2 O/S.

I got this all setup and working fine, with our dell servers and alerts to emails etc.

When I went to update the OME to 2.0.1, email Alerts stopped working. Discovery Inventory and monitoring all works fine as normal.

I checked the email settings in the OME interface and also tested the smtp server address from a Dell Server iDRAC and works fine, sending emails notifications from there.

When I run the troubleshooting Tool, I get a error:

Mailbox unavailable. The server response was: 5.7.1 Client does not have permissions to send as this sender
Also verify the "To" and "From" fields. (The TO and From is correct)

This is the same when viewing application logs in the OME interface. 

I don't know, if the reason why it doesn't send anymore, is the server certificate (https) is lost when doing the update. That the only thing I noticed, but don't see how that is related.

Thanks
