in thread sendmail working for me but not another

For details, see open and fork functions to start.

That open syntax forks the process (which I had long forgotten); $mailprog is run in child process. A pipe is opened to $mailprog in order to write to its standard input by writing to $mailhandle. (If the pipe-open syntax were -|, then that would be to read standard output of the command.)
