Cause

This has been reported as bug ID PPPM-14367.

Component installation on Debian-based systems installs sa-compile package as a Recommends dependency of SpamAssassin.
It brings in /etc/spamassassin/sa-compile.pre configuration with loadplugin Mail::SpamAssassin::Plugin::Rule2XSBody which actually causes these diagnostic messages.

Resolution

For Debian-based systems (include Ubuntu)

Connect to the server via SSH
Remove sa-compile

# apt-get purge sa-compile

For any system (Include RedHat/Debian-based)

Connect to the server via SSH
Use vi or any text editor to comment out the line loadplugin Mail::SpamAssassin::Plugin::Rule2XSBody in /etc/mail/spamassassin/ for RedHat-based systems or under /etc/spamassassin for Debian-based systems. Add # at the beginning of the line as below:

# loadplugin Mail::SpamAssassin::Plugin::Rule2XSBody
