Problem with sendmail (and mailx)
We have several RHEL 4.5 servers running Oracle. Each is a clone of the original. However I discovered that we can only send email from two (using the mailx command). I am not an expert on sendmail, however I have looked at every configuration file I can find to see if I can locate a difference between the servers that work and the servers that do not work and have come up empty. I looked at sendmail.cf and submit.cf, and their respective *.mc files, with no differences found. In the /etc/log/maillog file I found the following between servers (working and not working): Working: Jul 31 14:58:59 zn023 sendmail[30613]: m6VIwxY2030613: [EMAIL PROTECTED], ctladdr=root (0/0), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=32986, relay=mailhost [10.159.4.16], dsn=2.0.0, stat=Sent (Message accepted for delivery) Fail to send: Jul 31 14:48:50 zn019 sendmail[27586]: m6VImo9Z027586: [EMAIL PROTECTED], ctladdr=root (0/0), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=32985, relay=mailhost [10.159.4.16], dsn=5.0.0, stat=Service unavailable Does anyone have any insight to this and how/where the DSN values (Delivery Status Notification) is set, where I may look to find the root of this fail to send or any suggestions.

Re: Problem with sendmail (and mailx)
You should've received a DSN message in the mailbox of the user who tried to send (root) from ds019, or (less likely) in the mailbox of the Postmaster user (on most linux systems, this is equivalent to root anyway). The actual error you're getting will be in that message, and will be much more valuable for troubleshooting this error than the entry in maillog. My first guess is that your relay server (10.159.4.16) is not configured to allow relaying from any of your servers but the two that are work. If it is also using sendmail, the file defining this is usually /etc/mail/relay-domains. The DSN message (in the user's mailbox) should tell you in more certain terms, though. ok r. -Original Message- From: CHAPLIN, JAMES (CTR) [mailto:[EMAIL PROTECTED] Sent: Friday, August 01, 2008 2:02 PM To: LINUX-390@VM.MARIST.EDU Subject: Problem with sendmail (and mailx) We have several RHEL 4.5 servers running Oracle.
