I think you must have something trying to use the mail() function, or sendmail. I'm not an expert so not the best person to help you with this. If you're running WHMCS, maybe you have a customer/client who has recently installed a rogue script that's trying to do something on the server that it shouldn't?
I've a feeling that it's not a Sentora issue though and is something else to do with your server, but I could be wrong.
Good luck with it.
