Unable to relay to certain domains

I recently started having issues sending mail to certain e-mail addresses.  I get the following errors in maillog:

Apr  4 21:11:48 s1 sendmail[9456]: k352BlNC009456: from=<root@localhost.localdomain>, size=327, class=0, nrcpts=1, msgid=<200604050211.k352Blue009455@localhost.localdomain>, proto=ESMTP, daemon=MTA, relay=localhost.localdomain [127.0.0.1]

I get the following bounce back message:

Messages to other addresses seem to get delivered OK. I also have no issue receiving any messages.

I am running 8.13 sendmail on FC3 Linux.

Why has this suddenly started happening when I have had no issue prior to yesterday?

the "from" address on that email is root@localhost.localdomain, "localhost.localdomain" is not a valid domain name. TI.com's server probably were updated recently (when you started having the problem) to not accept mail from bogus domains.

You can use the command below to get transcript of the SMTP conversation.
[ it is necessary in sendmail-8.12+ to run it as toot]

( echo "subject: test"; echo ) | sendmail -v g-jones2@ti.com

If the remote server does not like "this host name" being "localhost.localdomain" (the most likely reason) then you can make you system report proper fully qualified domain name (fqdn) of "this host"  [it is dustribution dependended]. Command to get the name:
hostname --fqdn
hostname -f
