How to increase SpamAssassin Resource Memory Limit

Introduction

In most cases, the SpamAssassin memory limit doesn't need to be adjusted. However, if custom rules are in use, the configuration may need to be edited.

Procedure

1. Open the /etc/mail/spamassassin/local.cf file with your preferred text editor
2. Find the line that loads the ResourceLimits plugin:
   

   Mail::SpamAssassin::Plugin::ResourceLimits

3. Add or modify the resource_limit_mem option, and ensure it's below the line that loads the plugin.
4. Restart spamd:

   /scripts/restartsrv_spamd
