Hi Wesley,

I am using WebNms 5.1, no additional patches.
Please see the attached screenshot and exception from stderr.log on executing the policy.
At the moment, when policy started executing, there were 2 alarms matching the given criteria.

Mailserver.conf changes were done regarding smtp server details and account details which i cannot share as it is, but here is a sample.

<MAIL_SERVER_SETTINGS>
<ACCOUNT_DETAILS name="Default">
<FROM_ADDRESS>sudha_torli@procsys.com</FROM_ADDRESS>
<AUTH>false</AUTH>
<PASSWORD>text password here</PASSWORD>
<SMTP_SERVER>server ip here</SMTP_SERVER>
<SMTP_SSL>false</SMTP_SSL>
<PORT>25</PORT>
<TO_ADDRESS>sudha_torli@procsys.com</TO_ADDRESS>
<USER_NAME>sudha_torli</USER_NAME>

Looking forward to your suggestions.

Thanks,
Sudha
