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:
ad...@host.com shane
sh...@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
