You might try to get a slightly more meaningful error message like this:

open (MAIL, "|$mailProg") || die "Can't create pipe to $mailProg: $!";
[download]

$! should contain the error message as a string and die will announce more about the location of the error without the "\n" on the end. The documentation for both open and perlvar talk about $!.

Also, if you felt like doing things in the exceedingly modern perl-cool way, you'd write it like this:

open my $mailer, "|-", $mail_prog or die "couldn't open pipe to $mail_
+prog: $!";
[download]

Then $mailer will close itself when it goes out of scope and you don't pollute your package namespace with all-caps globs.

Yes - I did use the $! afterwards - sorry that wasn't in the code there. That's how I found out it was a "Bad File Descriptor" error message. Until then I didn't have anything. I saw the "|-" usage when I was looking into this problem too - maybe I'll change it to that. Any thoughts about the cause of the error message?

"Bad file descriptor" doesn't make sense as a failure reason for the code you posted. So I suspect your problem is something else. Please cut and paste some exact code that demonstrates the problem and the exact output that it produces.

- tye        

The "Bad file descriptor" error in $! is almost certainly a red-herring left over from some internal processing of no consequence to your code. Try printing $^E and see what that tells you?
