I have a fairly default Fedora 7 installation, certainly the sendmail
is just as it was installed.
How do I get sendmail to deliver mail to local destinations? The
system's hostname is home.isbd.net and it's connected to the Internet
via a router. I have a CNAME set up at the hosting provider that
hosts isbd.net to point at the static address of my ADSL connection.
When I send mail from my system to a local address it gets the
hostname added, thus mail gets sent to root@xxxxxxxxxxxxx,
postmaster@xxxxxxxxxxxxx, chris@xxxxxxxxxxxxx, etc. All of this
fails because sendmail attempts to connect to the SMTP port of
home.isbd.net, which isn't possible because my router's firewall
doesn't accept connections on port 25.
I don't want to open up port 25 and it seems a bit silly anyway to
send mail on such a long round trip. Is there any way I can tell
sendmail that home.isbd.net is localhost (or 192.168.1.1)? I have an
entry for home.isbd.net in my /etc/hosts file which is:-
192.168.1.1 home home.isbd.net
but obviously sendmail is doing a DNS lookup for home.isbd.net which
returns the 'external' IP address.
