If that happened, then I think Mahara has done its best to send out the e-mail and thinks it was a success. In which case, your next step is to examine your MTA's error log to see what it has to say about the e-mail - whether it even was given one to be sent, and whether it sent it.
Any suggestions for diagnosing the problem would be most appreciated.
A big thanks to Nigel for being awesome at responding to all of our queries!
