Hello XpanseStudio,

Based on our understanding, after upgrading to the latest version (2.1-19.1), messages are no longer processed by the email server and requires that the MagicSpam be disabled before messages are processed again. Did we understand you correctly?

To begin troubleshooting, please send us the output of the following terminal command ran as root:

cat /var/qmail/control/smtpplugins

Thank you.
