Thanks for your answer.
Yes, there are several PowerShell RBL and BASH RBL scripts around - but it would be great if Pulseway can integrate this as a built-in feature.
I think its very important for email servers.
We would like to monitor several email-servers.
Is there a way to monitor blacklists entries for these server like https://github.com/egeland/nagios-rbl-check ?
Thanks in advance and best regards
