Log mail an raise an OS X notification

mail-log-and-notify.sh

#!/bin/sh

# Mail logging combined with OS X notification.
# Uses terminal-notifier – https://github.com/alloy/terminal-notifier.

# Writes the whole message with header to the file, timestamp included,
# and raises a system notification with the message subject. The log
# file (LOG_FILE variable) is opened in the Console app upon clicking
# on the notification.
#
# To use with PHP instead of sendmail, alter php.ini like this:
# sendmail_path = /Users/…/…/mail-log-and-notify.sh
