sendmail is both an MTA and a commandline program for handing stuff over to the MTA. The problem with this way to sending emails from scripts is that it's hard to handle the errors reported directly by the sendmail commandline program. Once this step succeeds, the email is gonna be kept in the queue, retried etc. But if the sendmail refuses the email right away, you'll never know. You'd have to check the return value of the close(MAIL) to find out whether it succeeded and capture and parse the /usr/bin/sendmail's STDERR to know what failed. It's generaly safer to leave this to a module. Either one that calls the /usr/bin/sendmail in such a way that you do get the error info or one that contains the MTA via SMTP, not via the commandline program.
