[Mimedefang] DBI not working, use DBI; causing mimedefang to break 2.52

[Tory Blue]

I've made a bunch of tweaks recently and things are running well, however I
had a heck of a time getting all the various components of graphdefang to
install correctly, gd/GD to be specific and well I decided to abandon that
and just push the various things into a DB and then do some PHP or other to
create the reports I want to see.

However, the minute I add use DBI; to my mimedefang-filter things start
failing. Without it , I do a connect, helo mail from (forged) and am slapped
down, adding use DBI; I can helo/mailfrom/rcptto/data and then the system
just sits there, never finishes, never accepts the mail as being done, until
I remove use DBI and hup my Mail processes, then the system closes the
connections and delivers the forged email.

For example, until I remove use DBI; from my mimedefang-filter, the
connection does not end, sits here and I end up with slaves being used up
until there are no more, as inbound connections are waiting the 250 (hello
honeypot!)

relay=[10.5.1.76]

But I'm not leaving anything out, when I say, if I add use DBI; at the
beginning of my filter, things stop working (just the use DBI;, with no
other arguments, there is nothing calling DBI and it still breaks).

# -*- Perl -*-
#use DBI;  <--- commented out and it works, uncomment and mimedefang-filter
breaks, any ideas?
