If I did an 'exim -brw bob@???', it didn't match the entry
'bob@???' entry in the synonym file. Am I doing something wrong
there (or am I remembering my tests wrong - the machine I'm testing this
on is not 'here' at the moment). I was using Exim 2.10 on Linux 2.0.36
with Redhat 5.2 for my tests (if that matters).

Okey doke. I'll work out a better way to do it...

OK... I think that's things sorted then.
It shouldn't be a problem, because the actual files used will be script
generated, so I'll lower case as required when I do that.
Thanks for you help,
