freebsd stable - Mar 2004 - sendmail non-recoverable error

Have been searching Google to no avail and couldn't find anything on the
sendmail web site, so I'm hoping you can help.

Please cc: me in replies as I am not subscribed.  Thank you so much.

I run FreeBSD 4.9-STABLE.

Null message body; hope that's ok

I'll try to but AFAIK rr.com blocks my mails... all
these helpful anti-spam measures...

localhost unknown? Hmm, that's unusual...
Anyway, try to upgrade your submit.mc file:

8.12.7/8.12.7	2002/12/29
...
	CONFIG: Use FEATURE(`msp', `[127.0.0.1]') in submit.mc by default
		to avoid problems with hostname resolution for localhost
		which on many systems does not resolve to 127.0.0.1 (or
		::1 for IPv6).  If you do not use IPv4 but only IPv6 then
		you need to change submit.mc accordingly, see the comment
		in the file itself.
