If you are doing this frequently, or expect to get quite a lot of files 
listed, then this will be faster:
find /var/spool/mqueue.in -mmin +120 -print | xargs ls -l | more
as it will run the fewest "ls" processes possible, whereas the previous 
version will run 1 "ls" for each file output.

Using xargs makes a huge difference when you are doing an operation on a 
lot of files using your "find" command.
