OK, I forgot to mention those cases where the program includes parts
of itself in the output. However, there is no way an email sent
through postfix can be a work derived from the postfix code. The same
reasons apply here as to compilers. The copyright of object code
produced by a compiler is exactly the same as that of the source
file. Compiling the source code is considered use of the compiler,
and the output is not a work derived from the compiler.
