Recently “DSBL”, one of the DNSBLs used in SpamAssassin, changed their DNS to point to an unrouteable IP.
The lookup is still in the SA 3.24 rules MDaemon uses. If you have DNS service available set to Yes or Test, that might be slowing down SA processing. Try adding the following line to your \MDaemon\SpamAssassin\rules\local.cf file.
score RCVD_IN_DSBL 0
Once this is done, open a command prompt and type the following command to reload your SpamAssassin rules, and/or restart MDaemon;
echo. > C:\MDaemon\App\mdspamd.sem
