The maillog does show some cryptic [to me] errors:
Jun 28 16:36:55 box6 sendmail[1091]: l5SKaLF4001091:
to=bobgoodwin@xxxxxxxxxxxx, ctladdr=root (0/0), delay=00:00:34,
xdelay=00:00:30, mailer=relay, pri=989592, relay=[127.0.0.1]
[127.0.0.1], dsn=5.6.0, stat=Data format error
Jun 28 16:36:55 box6 sendmail[1091]: l5SKaLF4001091: l5SKaLF5001091:
DSN: Data format error
Perhaps someone can tell me what this means?
DSN = delivery status notification
Found this on google:
if your sending machine does not have it's own name/IPaddress in
its /etc/hosts file, it will cause the upstream target/relay host
to reject the message with something which means: "I don't know who
you are". The sending MTA sendmail then issues the error in the
maillog "...dsn=5.6.0 stat=Data Format Error". The fix for this is
to have a correct /etc/hosts;
The advice to fix your dns seems to be spot on.
