ConfigServer Community Forum

I searched but not sure I'm searching for the proper thing. I have one customer that has more than 30 users using email. They constantly are kicking off the firewall and I have to reset it.
Is there a way to restrict the firewall from blocking people using one domain on the server?
I understand this could cause trouble.

Only by IP or CIDR not by domain.

Put the specific domain in your csf.dyndns file, it might just do the trick
Also make sure you read the comments in that file before adding the domain :-)
