Output of UNIX commands

[Volker Moell]

Hi, there!

The output of UNIX commands traditionally will be substituted before
the line is parsed. For the example
  my_hdr X-Operating-System: `uname -a`
this is ok.

But is there a solution to get the output of commands which change
often, for example
  my_hdr X-Date: `date`

I tried to put it into a send_hook for ".", this doesn't work, too.


Thanks in advance for hints,
