Hello 
you use embedded perl .
I run also /~jpk/md-greylist and it works fine when I run mimefang whithout -E argument (embedded 
perl).
But  I have the same error ,: MySQL server has gone away , when I run mimedefang whith -E argument.
I haven't find any reason for this . If you have any ideas .
I run MD 2.44, mysql  Ver 12.22 Distrib 4.0.17, on hpux11.11
