Thanks for your suggestions Richard. There is no commonality with the email accounts; some organisational, some hotmail, etc. I have tried a test user with a hotmail account and received them fine. I am really err'ing towards it not being a moodle system issue but am unsure how to 'prove' that.
Would it be the case that if it appears in the report logs that an email has been sent, that I can rest assured that an email has been sent? Or is there something that could happen after that (within Moodle) which may be blocking it from being received by the NE tutor? In all cases the logs indicate that an email has been sent.
