Forum emails have stopped being sent out from my prehistoric moodle (1.6.x).
The reasons for email not being sent out (other than users not being subscribed) include
1) No cron at all (beginners often forget they need a cron)
2) The use of a noreply email address or admin email address that is outside your server's domain. Some servers prevent the sending of email with sender addresses that do not correspond to the server. This MAY also occur if Setting>Modules>Forum>forum_replytouser: is yes and the server does not even allow 'faked' reply addresses but that is just a guess.
3) Moodle 2 has a different address for the cron to previous versions of moodle. moodle/admin/cron.php is now moodle/admin/cli/cron.php thought most of the documentation page mentions the former address.
4) Disk space is full.
5) Incorrect smtp setting (try php mailer by making the setting blank)
6) A problem with another module (e.g. a problem with the journal module) that stops the cron before it gets to the forum module.
7) A rather arcane problem with servers that are set up like gmail and require a modification to the code as would be made when using gmail as the smpt server.
I have tried all the above except the last. Any other suggestions?
My cron says
Starting activity modules
Processing module function assignment_cron ...done.
Processing module function forum_cron ...processing post 253 done.
Finished activity modules
And then
Starting activity modules
Finished activity modules
When I hit the cron again but no email is sent out.
