Our lecturers are using the news forum in their courses for important emails to their students. They therefore want to be able to get reassurance from me that these posts are really emailed out to all the enrolled students. In order to be able to give this assurance I want to start to log the output from cron.php which does report how many mails were sent out and shows up any error messages.
To have an even easier way of seeing if there was a problem with sending the mails for a particular forum post I propose to set the "mailed" column of the mdl_forum_posts table to 2 instead of 1 in the case of a problem. That would mean that its size would have to be increased from TINYINT(1) to TINYINT(2). No logic within Moodle would have to be changed. Are there any objections to this change? If not I would implement this. But perhaps there are better proposals?
