maildrop, and more generally all delivery agent programs other than the
built-in maildir/mbox ones in qmail-local, are "integrated" into qmail by
incorporating a delivery instruction in a .qmail file. A program delivery
line looks like this:

|program-name-or-path [args...]

That tells qmail-local to invoke that program with the message being handed
off attached to the programs stdin. So the program reads the message from
stdin and does whatever the program is supposed to do with it.

There's a special case where the system administrator can make the system-wide
default delivery instruction such a program delivery, in which case it won't
show up in the .qmail file(s).

See the qmail manpages for more details -- `man dot-qmail` for starters, then
follow all the "see also" links in that one.

It can't be that either - the global file:

/etc/maildroprc

does not exist and the only uncommented line in ~/.mailfilter is:

logfile "$HOME/.getmail/.maildrop.log"

but that just tells maildrop where to put the output . .

Thanks,

Phil.

Like I said, "maildrop" is not mentioned in any file under:

/var/qmail

Thanks,

Phil.

Many thanks!
