Ok, I see reverse DNS is simply reversing the process, not sure how that
affects me?
The maillog does show some cryptic [to me] errors:
Jun 28 16:36:55 box6 sendmail[1091]: l5SKaLF4001091:
to=bobgoodwin at wildblue.net, 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?
Maybe I should just wait until I've installed Fedora 7. It may be
different then.
