RELAY Alert, spammer bombing our server every 5 minutes, please help
Posted: 24 Sep 2015, 23:29
Hi All,
I have a Cpanel/WHM server running CSF & LFD and we are getting pounded with spam coming in to our hosted email accounts, about every 5 mintues, 24/7. These are coming from outside of our server TO email addresses on our server.
I set the RT_RELAY_LIMIT to 2 messages and Permanent Block but the senders keep changing the source relay IP, below is a sample.
I can't figure out how to stop these relays, does anyone have a suggestion for this?
Thanks
