Top Forums Programming Notification email in C program, via system call? or? Post 302503392 by achenle on Thursday 10th of March 2011 11:19:06 AM

First, whatever is hanging the child processes you spawn off with your call to system() will probably cause the same problem no matter how you get around it.

Second, what the mail program does is pretty complex. Duplicating that would be a lot of work, and you won't do it as well as the mail program does.

Finding out why "echo ... | mail ..." is so slow is your best option.

If you're on Linux, run the mail utility under strace. If Solaris, use truss. Look at the man page for the one you need to use, then look in the output and find out where the mail program is taking so long.
