Exim config question

[glhenni@cs.sandia.gov (Gary L. Hennigan)]

I'm in the process of getting a little home network set up. One of the
hosts, call it mach2, won't have a connection to the internet, just
to other hosts on my home network. The other host, call it mach1, will
occasionally connect to the internet via dialup. I have mach1 all set
up but can't seem to get mach2 to forward all the mail to mach1. In
fact I can't get mach2 to deliver mail directly to mach1 at all.

What I want to do is set mach2 so that it uses mach1 as a smarthost. I
think I got that right in my exim.conf (configuration 2 from the
debian installation) but I can't seem to make it work. When I send
email to, for example, glhenni@mach1 I get this in my exim mainlog:

1999-07-25 10:38:36 118R4n-0000B0-00 == glhenni@mach1 routing defer (-32): retry time not reached

or

1999-07-25 10:39:47 118R4n-0000B0-00 == glhenni@mach1 R=smarthost defer (-1):

I get the same thing if I send the email to glhenni@mach1.home.domain

Also, something's not quite right with mach1. If I connect manually,
eg., telnet mach1 smtp

and type rcpt to: glhenni@mach1

I get:

550 relaying to <glhenni@mach1> prohibited by administrator

but if I do rcpt to: glhenni@mach1.home.domain

it works.

Any ideas?

Thanks,
Gary
