sendmail....!

[derek b smith_1]

Hi All,

I am getting this ole sendmail error. I searched and read many prior posts to no avail.
As a sysadmin habit I like to disable sendmail daemon, and still use the smart relay option which I am but I still get this error.

Aug 30 09:51:56 jude sendmail[6394]: o7UDpuC6006394: to=andrew.xxxx@cbc-companies.com, ctladdr=oracle (501/501), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30778, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1]


My other hosts do not have this issue.
Below are some configs from my problem host:

# sendmail -bt

Enter

mailhost
> $j

I suppose I could just config it to send-only but...rather not.

Shalom,

if you disable the sendmail daemon, which is a good job, you need a cron job to run the queue once in a while and get the mail off the system.

After you get some mail in the outbound queue, run this command:

sendmail -v -q

Post a snippet if you get unexpected results.

I did run sendmail -v -q with no output and same results:

by the looks of things you are relaying to the localhost.. is that your intent ?

if so, then you need to always run the sendmail daemon in order to recieve that mail..

Not sure what you are trying to accomplish.

you do not need the sendmail daemon running in order to send any email..only to receive.. and on the occasion where the outgoing mail gets queued for some reason ( this is where you run the queue runner via cron. )

Tim,

Thanks for the reply but you are wrong.
My relay host is mailhost per

# sendmail -bt
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter

> $S
mailhost

above.

I updated it to another relay host, another exchange server and I still get the same error.

# sendmail -bt
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter

> $S
cbcsmtp.cbc.local.


Any other ideas?

[derek b smith_1]

see attachment for debug mode output.

thank you!

[Tim Nelson]

must have missed that.. was reading this line in the log output.

stat=Deferred: Connection refused by [127.0.0.1]

[Patrick Wallek]

It also appears to me that it is not getting to the relay host.

What does "nslookup mailhost" return? Does it return the IP address of your relay server or does it return "127.0.0.1".

What if you modify your sendmail.cf file and insert the IP address of your relay server rather than the hostname?

[Steven E. Protter]

Shalom,

Short term, you might want to turn on the sendmail daemon. Sendmail has been re-structured in recent years to make it harder to queue mail without the daemon running.

Which is the recommended way of running a Unix server.

I have it turned back on in send mode only, but when I change relay to the IP it still fails.
