Actually, I lie. The way you're doing it "sed <filename" can only use 
one file. Sed will work on many files, like almost any UNIX utility:

  sed .... /path/to/spooldir/*

(And that _is_ in "man sed".)

But you'll only get one _output_. Usually you're processing one file and 
doing something separate with its result, then processing the next. Etc.  
In this context where you're sending many email messages. If you're 
doing that...
