By default, SpamAssassin will not check emails larger than 250 KB. This parameter is set to prevent SpamAssassin from generating a large load on the server.

Requirements

Before you start, this article has the following dependencies:

• You must have SSH access set up for root or a sudo user.
  • Connecting via SSH to your server
  • How do I enable root access to my DV?
  • How do I disable SSH login for the root user?

Instructions

If you would like to change this setting to a higher value, you can edit the following file:

Next, change this line to a higher value:

MAX_SIZE=256000 # max letter size to filter

SpamAssassin will use the new value immediately with no need to restart any services.
