Hi all,

I'm having difficulty getting sendmail set up on my server.  I can send 
and receive to localhost and I can send to external networks but I can 
not receive from external networks (I receive a 550: Address rejected).  
Netstat says sendmail is listening on port 25 but I cannot telnet to it.
When I do a port scan of the server, nmap does not show anything on port 
25 but does show smtp on 587.

As far as configuration goes, I added my hostname to 
/etc/mail/local-host-names and created a /etc/host/virtusertable that 
looks like:

admin@host.com    shane
shane@host.com    shane

then I ran 'make all install restart' .

A couple more things that might be useful, I have a second ethernet 
interface that I am guessing my provider uses for maintenance (internal 
lan) and I shut my firewall completely off while testing.

The output of netstat and (filtered) nmap is:

netstat -a | grep smtp*:

*tcp6**0    0    0 *.smtp     *.*    LISTEN
tcp4**0    0    0 *.smtp     *.*    LISTEN
