"CHAPLIN, JAMES (CTR)" <[EMAIL PROTECTED] To sociates.dhs.gov> LINUX-390@VM.MARIST.EDU Sent by: Linux cc on 390 Port <[EMAIL PROTECTED] Subject IST.EDU> Problem with sendmail (and mailx) 08/01/2008 05:01 PM Please respond to Linux on 390 Port <[EMAIL PROTECTED] IST.EDU> 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.
