Thanks. I can't try that until I get home this evening (the sysadmin here
at work has blocked the ssh port I use).
However, what puzzles me is why the mail goes outside the network at all.
I'm sure that when I had this working previously (on F15) it was just a
system mail delivered directly.
I'm sure I've got something wrong in my setup but I can't see where I'm
going wrong.
This has actually caused a massive problem for me as I am now listed on
several blacklists and the mail I send from my account often disappears
into the ether - presumably because my correspondent's ISP take an
aggressive approach to using blacklists to block mail.
Once I have sorted this out I will have to ask how to get off these
blacklists!
Thanks
Mark

I don't know and have not looked at this code in a long time, there could be
a
bug in the way it was implemented.
