[vexim] Changing the SA config

[Aaron Eldridge]

Hi Adam,
             Thank for your reply, I did eventually get it working, I 
basically way expecting it to work from a single config file  instead I 
had to understand more about how exims routers were working.

I should have posted a message to say I got it fixed but seeing as no 
one ever replied or asked anything else I assumed the mailing list was 
dead. It's a shame vexim's doesn't seam to be being worked on any more I 
find it very very useful :)
