help please: MX problem ["did not issue MAIL/EXPN/VRFY/ETRN ... MTA" ??]
The Derfer
The relay I'm sending to endlessly 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):

It makes readers wary, if both logs correspond with each other.

Is the server name of the greeting message the same on both servers?
When you telnet smarthost smtp and telnet dbserver smtp.
-ska
The Derfer
telnet dbserver smtp from the dbserver itself gives me access to
sendmail port there.
telnet smarthost smtp from the dbserver does nothing; there's no host
defined as "smarthost"
anyplace.
The Derfer
logging up to level 15), the following.
Which still begs the question WHY the dbserver is not issuing the
"MAIL" command to initiate transfer??!!
It just does a "QUIT" (none of my other servers do this!). What's
wrong?
Thanks in advance for helping.

No, it isn't.
You can see why I'm so confused.
If I telnet dbserver 25 it will say "Connected to dbserver" and then
"220 localhost.localdomain ESMTP Sendmail 8.13.8/8.13.8"
If (from the dbserver) I telnet mailhost 25 I get:
"Connected to mailhost."
and then:
"220 localhost.localdomain ESMTP Sendmail 8.13.8/8.13.0"
Thanks for helping.
I appreciate it.

Yes, the server name of the greeting message is the same on both servers.
Both dbserver and mailhost claim to be 'localhost.localdomain' in the 220
greeting message. Change one (or both) of those.

Where?
Is /etc/hosts the only place?
Is there a sendmail config file that can alter this for sendmail
purposes
only?
Thanks for the advice.
Grateful.

Any of:
0. Setup proper reverse dns resolution for the primary ip address of the
box. Sendmail by default will probe the interfaces and use rdns to get
the
name.
1. Add the FQDN to /etc/hosts.
2. Add define(`confDOMAIN_NAME', `FQDN')dnl to the Sendmail macro config
(.mc) file. Build and install the Sendmail configuration file (.cf).
3. Manually change the Dj line in sendmail.cf to configure $j.

The Derfer
line next to it's
actual IP address.
Should it also be on a line with 127.0.0.1 (which has the
localhost.localdomain name) in that
file as well?

Looks like sendmail considers the loopback interface as your primary
interfaces. I would follow Carl's advice #2.

The Derfer
I put (exactly) this:
define(`confdomainname.com', `dbserver.domainname.com')dnl
at the very end of sendmail.mc on dbserver
then "m4 sendmail.mc > sendmail.cf" (also on dbserver)
then restarted the daemon on dbserver.
And the exact same problem remains. All error messages are the same.
("domainname" above is anonymized but it's the company name).
Did I do something wrong?
Mail relay server still says: ".... did not issue MAIL/EXPN/VRFY/ETRN
during connection to MTA"

OK thank you: that helped considerably.
Now some e-mails go out. To gmail, for example, they always go out
perfectly directly
from a "Mail us...@gmail.com" command line from dbserver.
Other times it's less predictable. See here:
Dec 11 13:57:13 mail-relay sendmail[16318]: nBBIvADZ016299:
to=<us...@comcast.net>, delay=00:00:03, xdelay=00:00:03, mailer=esmtp,
pri=120543, relay=mx2b.comcast.net. [76.96.30.116], dsn=5.0.0,
stat=Service unavailable
Dec 11 13:58:43 mail-relay sendmail[16496]: nBBIwh7A016496:
to=us...@comcast.net, ctladdr=user (1007/1007), delay=00:00:00,
xdelay=00:00:00, mailer=relay, pri=30045, relay=[127.0.0.1]
[127.0.0.1], dsn=2.0.0, stat=Sent (nBBIwhcv01649 Message accepted for
delivery)
The first line is an e-mail "Mail us...@comcast.net" from the dbserver
command line
The second one is mailed the same way except from the mail relay host
itself.
Also curious is a different error, that of "User unknown":
Dec 11 15:27:08 mail-relay sendmail[27330]: nBBKR5nv027319:
to=<us...@oracle.com>, delay=00:00:02, xdelay=00:00:02, mailer=esmtp,
pri=120552, relay=rcsinet11.oracle.com. [148.87.113.123], dsn=5.1.8,
stat=User unknown
Pertaining to the above, it originated as "Mail us...@oracle.com" from
dbserver's command line as user "oracle".
Directly from the mail relay server's command line it reaches its
destination.
Does anyone know how to fix this?
Thanks again for all the help. I'm way ahead of where I was last
week thanks to everyone's
input.

This is a reply from mx2b.comcast.net. See RFC 1893 what 5.0.0 means.

This is a reply from your own server @ mail-relay telling you it has

What is curious? rcsinet11.oracle.com. said: RFC1893 permanent failure
"Bad sender's system address". It is its right as to tell you, that
the recipient does not exist.

But why would that error happen the mail is sent from the dbserver and
not
if sent from the mail relay box itself?
I get two different results.
