The relay I'm sending to continually has this in its /var/log/maillog
EVERY time I send an e-mail
from one particular host (a dbserver with no dns):


Nov 13 11:15:13 mailhost sendmail[4199]: nADGFDxC004199: dbserver
[10.156.90.13] did not issue MAIL/EXPN/VRFY/ETRN during connection to
MTA

Corresponding entry in /var/log/maillog on the dbserver (yes, times
are a little out of sync but I don't
see what that has to do with anything):

What the heck could be wrong?? I've stared at this for more than 20
hours and still no results.
This is as close as I've got.
Please help.

You've got a local configuration error, as the Delivery Status Notification
(DSN) clearly states.

If you post the results of

egrep -v "^dnl|^$" sendmail.mc

then someone will be better able to advise you.

So what's in your /etc/mail/local-host-names file?

Nothing's in that file on the dbserver. Nothing's in it on the
mailserver relay either.
Other hosts send to the relay fine (Solaris hosts) but these RHEL5
hosts don't
do it right. My RHEL AS/3 boxes even used it fine until I replaced
them with
new RHEL5 boxes.

On the mail relay server the file /etc/mail/relay-domains has EVERY
possible
permutation (FQDN and not) of the dbserver's name in it but still no
go.

What do you suggest? I never needed to populate that with anything in
older versions of RHEL AS/3.
This is RHEL5.
