One of my boxes which was working a few days ago has stopped sending
mail. I found this test in the exim wiki:
catherine ~ # exim -bt michael
michael@??? is undeliverable: Unrouteable address
<-- michael@???
Here's a more complete attempted transaction:
catherine ~ # telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

I have tried everything I can think of to get this to work, even just so
that it will mail out my logwatch reports, but nothing's worked. Can
anyone help me? This box runs Gentoo with kernel 2.6.19-gentoo-r5 SMP,
has public IP address 70.234.122.251, and exim-4.67 with the following
USE flags:
catherine exim # emerge -pv exim
These are the packages that would be merged, in order:
Calculating dependencies... done!
