Spamd Startup Configuration

We advice to use the following settings in WHM/cPanel (Spamd Startup Configuration)

Allowed IPs:

• 127.0.0.1
  This restricts spamd to only accept connections from the local server, enhancing security by preventing external IPs from connecting to the spamd service.

Maximum Connections per Child:

• 300
  This allows each spamd child process to handle up to 300 connections before being terminated. This is a balanced number that ensures performance without overloading the server.

Maximum Children:

• 5-10
  This controls how many spamd child processes are started. A range of 5 to 10 is usually sufficient, depending on your server’s capacity and email traffic volume. You can start with 5 and increase it if you notice spamd being overwhelmed.

TCP Timeout:

• 30 seconds
  This is the time a connection can remain idle before being abandoned. Thirty seconds is a good default that provides flexibility without holding onto resources too long.

TCP Child Timeout:

• 300 seconds (5 minutes)
  This is the time a child process will wait before abandoning a connection. A 5-minute timeout gives enough time for processing without leaving resources tied up unnecessarily.
