In The Icewarp Mail Server, you can create Different patterns that can be used in other parts of the system. An example of this is to create a Firewall Pattern that can be used to block connections from a specific location. (or to allow communication from specific locations). Below are the steps to create this example:
1- Go to Main Menu > System > Advanced > Patterns tab
2- Add a new pattern.
3- name it firewall.
4- In the Items, put the IP address that you want to be part of the pattern there.
6- Go to Main Menu > System > Services > "right clck any process" > Properties > Access tab .
7- Check the option to "restrict access to all services"
8- Change the Access type to "deny".
9- In the box for the IP addresses, put in [firewall]save the changes and then restart the SMTP services.
