[Observium] [observium] facing problem in email alerting.

Hello Guys, I am facing a problem regarding Observium Alerting.

Few days ego I have enabled alerts and configured to send to couple of specific email ids. Configured those email Ids in .php file as well as in GUI.

Due to some reason I have removed those email Ids to stop sending alerts. Now Observium starts collecting email ids from 'snmp contact' configuration of device and sending alerts to this email id.

Please let me know what to configure so that Observium would not be able to send emails to the email id which is configured in snmp contact of network device ?

Thanks,
