[maildropl] Default maildrop script

[<ro...@di...>]

Im on Fedora Core 2 using qmail with qmail-scanner, along with
Spamassassin 3.0.1 and maildrop. Im also using vpopmail with qmail and Im
trying to create a default maildrop script for each domain I create in
vpopmail. The problem is it gets overwritten anytime someone makes a
change to the qmail-default, such as selecting a catch all account.

Right now the .qmail-default file looks like this when I want it to point
to my mailfilter path: (I changed the path to a generic path for security
purposes)

| preline maildrop /path/to/mailfilter

But the second someone makes a change vpopmail overwrites the
.qmail-default file. Is there a way to make the mailfilter file defaulty
be used by all domains in vpopmail and it wont get overwritten?

Thanks
Robert
