How to increase SpamAssassin Resource Memory Limit

Question

How do I increase the SpamAssassin memory limit?

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

Answer

1. Open the /etc/mail/spamassassin/local.cf file with your preferred text editor

2. Find the line that loads the ResourceLimits plugin:

   CONFIG_TEXT: Mail::SpamAssassin::Plugin::ResourceLimits

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

   # resource_limit_mem 536870912

   Note: The resource_limit_mem limit value is in bytes.

4. Restart spamd:

   # /scripts/restartsrv_spamd
