On our university Moodle site, messaging has been disabled sitewide in order to discourage mis-use of it.
However, it is still possible for a teacher to send a message to selected students. In a course, I go either to Participants or to Reports and I check the names of the students I want to send a message to. The selected users (students and, possibliy teacher) do receive the message through their personal e-mail system, not on the Moodle messaging system, since it is disables. This is fine.
Just one small hitch: at the bottom of the message received through their normal e-mail system, there is a link: This email is a copy of a message sent to you at "UniversityMoodleSite" something like this: <a href="http://UniversityMoodleSite/message/index.php?popup=1">
However, if one clicks on that link, one is taken to the Uni. moodle site and the following error message is displayed:
Messaging is disabled on this site
Suggestion: In order to retain the "collective messaging" facility when messaging is disabled site-wide, there should be a mechanism in Moodle to detect this disabling and to not print the This email is a copy of a message sent to you at "MoodleSiteName" link a the bottom of messages sent to e-mail systems.
What do you think?
