Thanks for that. I've just tried using $header_from: in my exim 
authenticator in client mode when talking to the provider's SMTP server 
in smart relay mode (instead of $sender_address) - but for some strange 
reason it just won't work. I've poured over the exim logs in debug mode 
- and so far I can't make sense of what is happening. I'll try some more 
to figure it out and get it working.
