Philip - that's brilliant!  Thank you very much!

Ah...  Are you saying that, now I have it set up on Fastmail, if I send through their SMTP server they will proxy to the appropriate third-party one?  If so, that's brilliant, and means I don't need to bother with this!

(I could just try it and look at the resulting headers, but I didn't want to undo the nice system you've helped me set up yet!)

All the best,
