I've just hit upon a potentially very serious problem for me. I have a course with 400 members. They are split into many groups of about 8 users. In moodle 1.6.2 non-editing teachers could only see their group members and would only receive mail from their group members, not any other groups. My first surprise was to find that non-editing teachers could see all other groups, so I've solved that by changing moodle/site:accessallgroups to "prevent". However, a potentially very serious problem has arisen. Non-editing teachers whom don't belong to a group to which a message is posted are receiving the emailed posting from that group. This does not reflect the behaviour from moodle prior to roles being introduces and I cannot for the life of me work out which permission flag to switch to solve this problem. Non-editing teachers whom have moodle/site:accessallgroups set to prevent should not be receiving email copies of postings from groups they don't belong to else it will be a) annoying for them, b) defeats the purpose of group forums and breaks privacy rules.
Please help me, before people break down my door...!
