Well, with smail when this happens it's because smail is looking for
MX DNS records, not A DNS records; to get smail to use the hosts file
you need to tell it to use the gethostbyname router for certain
locations (you do this by having a gethostbyname router with the
"required" attribute before your other routers).
I suspect that sendmail is doing the same thing - that is, looking for
MX DNS records, which means bypassing the hosts file. You need to
somehow tell sendmail to just use gethosbyname() instead of DNS stuff;
maybe there's a way to have sendmail look for address (A) DNS records,
which should amount to the same thing as using gethostbyname().
