I also used

system("export "METAMAIL_TMPDIR=/home/tst/tmp");

but this also does'nt work.

I'm not sure that environment variable that you set from CGI, will stay after CGI quits ...

From the Perl FAQ:

I {changed directory, modified my environment} in a perl script. How come the change
disappeared when I exited the script? How do I get my changes to be visible?

Unix

     In the strictest sense, it can't be done -- the script executes as a different process from the shell it was started from. Changes to a process are not
     reflected in its parent, only in its own children created after the change. There is shell magic that may allow you to fake it by eval()ing the script's
     output in your shell; check out the comp.unix.questions FAQ for details.
