The traditional Unix tool for this job is procmail[1].  You can configure it to process all incoming mail in an account with a shell script -- decoding the attachment and saving it to a file would be very easy to do, assuming the server is also a FTP or web server.  Of course, the script could also just decode the attachment and load it directly into MySQL.
