Virtualmin update stomped on my procmail config.

I just ran the apt-get update to install 3.56 this morning, and it changed my procmail file from using Maildir back to Mbox. The lines:

ORGMAIL=$HOME/Maildir/
DEFAULT=$HOME/Maildir/

got changed to:

ORGMAIL=/var/mail/$LOGNAME
DEFAULT=/var/mail/$LOGNAME
