Ok I've tracked this down to a problem with the Users table - it doesn't seem to save the
Email Options Reply-to name Reply-to address fields in the users table - but then it doesn't seem to use them anyway - If you manually add an email1 to your user it makes the send button active - and sends or at least tries to, at least i can see an error now!
I added in Users.EditView the Email1 binding and in Users.DetailView and now that works fine - was probably just overlooked in the build
Meanwhile I will see about the Reply-to Name and Reply-to address - it would seem to me that these settings hould be the ones that the email sending grabs rather than the users email1.. back to the studio...
Ok I've put in the correct settings and it does in fact now work as expected - need to think this through a bit more because as the headers don't match the emails generated are being caught by spam and junk filters - notably in outlook.
The email options probably needs to be adapted to use the users own pop3 accounts or exchange - or generic ones like "info@" which would have to be selectable somehow. Anyway the point is that it does work which should be deemed to be a GOOD THING
