Log Message:
Update to 4.0.9. From the changelog:

This version fixes a bug in the address parser that was preventing
some sender/recipient whitelist/blacklist entries from matching.
Thanks to John Devenport for reporting this one. This version also
fixes a bug in the "config-test" feature that prevented spamdyke
from finding its own binary when the file is not in the current
directory. Thanks to John Hallam for reporting this one.
