Help! Mail to 'localhost' not staying local

[V.I.Victor]

Somthing changed -- literally overnight!  Or perhaps, some old problem is just showing up.

All my log reports, et cetera are stuck in mqueue.

Example -- for years, the following line has been in root's crontab: (sorry if folded)

@reboot /bin/echo "reboot" |/usr/bin/mail -s "start-up at `date`" root at localhost


It has worked without any problems delivering an email indicating start-up time.


Now...  Well, here's some lines from the 'mqueue' file:

H??Received: from zebra.athome.net (localhost.athome.net [127.0.0.1])
        by zebra.athome.net (8.13.3/8.13.3) with ESMTP id l33AFhEA000481
        for <root at zebra.athome.net>; Tue, 3 Apr 2007 06:15:44 -0400 (EDT)
        (envelope-from root at ld2.networksolutions.com)
H??Received: (from root at localhost)
        by zebra.athome.net (8.13.3/8.13.3/Submit) id l33AFhqS000433
        for root at localhost; Tue, 3 Apr 2007 06:15:43 -0400 (EDT)
        (envelope-from root)

It seems that my local network name of "athome.net" is being "evaluated."

It's been around since 1999, but was updated yesterday.


I'm assuming I did something wrong years back in my 'sendmail' setup.  At this point, I certainly don't remember the whys & hows of what I did!

Could someone *please* help?

Thanks! V
