Ah, you are running into the problem that in ePN STDOUT does not
go to STDOUT.  It is redirected to an array inside of p1.pl.

The best way to fix this is to not use the "|" on the commandline.
Use:

open(CMD,"|/bin/mail arg1 arg2...");
print CMD "Perl here.\n\n";
close(CMD);

or if you really need to use the commandline pipe, then you have
to not use ePN (ie. use "/usr/bin/perl script_name | /bin/mail ..."
