I'm not sure this is a sendmail issue at all.
If it is it is certainly not solely sendmail which is at fault.
Allow me to quote:
ed@xxxxxxxxxxxx
... Deferred: Name server: mccorduck.ws.: host name
lookup failure
Message could not be delivered for 4 hours
Message will be deleted from queue
it seems like a DNS lookup error. Indeed
$ host mccorduck.ws
fails completely.
$ dig MX mccorduck.ws
; <<>> DiG 9.2.2 <<>> MX mccorduck.ws
;; global options: printcmd
;; connection timed out; no servers could be reached
The website doesn't appear to exist either.
Who hosts your DNS? Can _you_ ping mccorduck.ws? I certainly can't. It is no
surprise that your mail is not delivered if the AOL and other mail servers
cannot find YOUR mail server on the internet.
so on which machine are you running sendmail? The same as your pop server?
(well, actually you'll be running it on any and all RH boxen by default, but
as roger states, it will only accept mail for delivery from localhost - this
is why you can send mail out, but can't receive it.)
actually I would read the HOWTO that rodolfo has posted further down this
thread, but here's a quick runthrough. do not assume that this is secure -
just use it for a five minute test.
to get sendmail to listen to ANY host (the simplest, but not the most secure,
be aware of this. You can further specify what to do with mail from/to
different hosts in other config files)
cd /etc/mail
vi sendmail.mc (or use pico -w, or some other editor)
search for the line
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
comment it out thus:
dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
note that it isn't a # - this is an M4 macro file
then:
a) backup your original sendmail.cf file (the file actually read by sendmail)
cp /etc/mail/sendmail.cf{,.bak}
b) generate a new file from your recently edited sendmail.mc file:
m4 /etc/mail/sendmail.mc > /etc/mail.sendmail.cf
c) restart your mail server
service sendmail restart
Now test your email again:
in a terminal window:
tail -f /var/log/maillog
then try sending an email to yourself from elsewhere and read what the output
in the terminal tells you. It will tell you if the mail you sent was accepted
for delivery.
If this was not the problem, put the original setting back.
