How is your host file setup do you have myserver.mydomain.org in there
and is it using you NAT'd address?

I have been searching the archives of this list and google and not yet
found the solution to my problem. It seems like this is a common
problem with sendmail on new installations of Fedora, so I am
frustrated by not finding a solution that works for me. I would really
appreciate any help.
I had a RedHat 7.3 installation working properly, both sending and
receiving mail with sendmail. I wanted a clean Fedora install, and
since then I can send, but not receive mail.
I have modified /etc/mail/sendmail.mc and commented out the line
dnl # DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
then ran make -C /etc/mail and restarted sendmail with service
sendmail restart.
I also modified /etc/mail/access and added
localhost.localdomain RELAY
localhost RELAY
127.0.0.1 RELAY
myserver.mydomain.org RELAY
then restarted sendmail.
I have a 4 port linksys as a router/firewall between my cable modem
and my server (and 2 other PCs). Port forwarding is enabled on the
linksys to allow http traffic, and smtp on port 25 to be forwarded to
the server - which was all working correctly before the Fedora install.
I ran ethereal and watched connections, not that I understand much of
the packet info. I see connection attempts, but external mail servers
never complete a connection. The typical pattern seems to be a remote
server sends a SYN on port 25, I reply with SYN,ACK. Remote sends a
SYN, I send 2 SYN,ACKs. Remote sends a SYN, and I send 3 SYN,ACKs, and
eventualy the rmote gives up.
From any PC inside my network I can telnet to the server on port 25 and
issue basic smtp instructions. I can do the same locally with
127.0.0.1 e.g.
# telnet myserver.mydomain.org 25
Trying 192.168.1.12...
Connected to myserver.mydomain.org.
