Take a look at Pure-FTPD. Here's the relevant snippet of the  
configuration process:

--with-uploadscript: since 0.98, Pure-FTPd has a nice feature regarding
uploads. Any external program or script can be automatically called  
after a
successful upload. It needs another program installed by the Pure-FTPd
package, called 'pure-uploadscript'. Check the man page for more info  
about
this.

 From pure-uploadscript(8):

NAME

pure-uploadscript - Automatically run an external program after a  
successful upload

SYNTAX

pure-uploadscript [-p </path/to/pidfile>] [-B] [-g <gid>] [-h] -r  
<program to run> [-u <uid>]

DESCRIPTION

If Pure-FTPd is compiled with --with-uploadscript (default in binary  
distributions), and if the -o (or --uploadscript) is passed to the  
server, a named pipe called /var/run/pure-ftpd.upload.pipe is  
created. You will also notice an important file called /var/run/pure- 
ftpd.upload.lock, used for locking. After a successful upload, the  
file name is written to the pipe. pure-uploadscript reads this pipe  
to automatically run any program or script to process the newly  
uploaded file.
