Hello Support,
For now, I'm just trying to test to see if the "Send Mail" feature can work in order to send alerts. I do understand, that work sending to our company email, it is blocking it & I will have to ask our Email Admins to allow from this server, but before I reach out to them. I would like to check if my Nagios server can even send emails to an email using the "Send Mail" feature, because idea is too not use any SMTP server weather it is internal or external, I would like to only use the "Send Mail" feature & no SMTP. Therefore, when I try to send to my personal Gmail, I was under the impression it will send directly to my Gmail & doesn't need to involve my internal SMTP.
By the way, when I do try to send it says email has successfully sent, but the logs under /var/log/mailog file says the following below, whats the issue here below?
