sendmail issue

MikeL_4 — Tue, 13 Jan 2009 17:58:08 GMT

I have a new Red Hat Version 5 server that I have configured sendmail on to be able to send mail only... Issue is it isn't working, as I receive message: Connection refused by [127.0.0.1]

I have it working on several other servers but this one is a mistery so far...

What I see with sendmail that is running is:
[root ~]# ps -ef |grep sendm
root 4258 1 0 11:01 ? 00:00:00 sendmail: Queue runner@01:00:00 for /var/spool/mqueue
smmsp 4268 1 0 11:01 ? 00:00:00 sendmail: Queue runner@01:00:00 for /var/spool/clientmqueue
root 5721 4557 0 13:10 pts/1 00:00:00 grep sendm
[root ~]# telnet localhost 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
[root ~]#

And on my other working servers I see:
[root@ ~]# service sendmail status
sendmail (pid 6486 6476) is running...
[root ~]# ps -ef |grep sendm
root 6476 1 0 Jan08 ? 00:00:00 sendmail: accepting connections

^]
telnet> quit
Connection closed.
[root ~]#

I don't understand what isn't starting correctly that I don't see: sendmail: accepting connections running....

I want to see the output of the following commands:

netstat -an | grep ":25"
service iptables status
getenforce
service sendmail restart && tail /var/log/maillog

Can you describe what is the configuration you did to "send mail only", as you can see, the sendmail daemon is up but is not running on any interfaces, as displayed by the "netstat -an" command.

In file /etc/mail/sendmail.cf added:

DSsmtp:mailhost.convergys.com
and
DHmailhost.convergys.com

In /etc/mail/sendmail.mc added:

define(`MAIL_HUB', mailhost.convergys.com)dnl
define(`SMART_HOST', smtp:mailhost.convergys.com)dnl

In /etc/mail/submit.mc added:

FEATURE(`msp', `[mailhost.convergys.com]')dnl

If you modify the sendmail.cf file, there is no need to modify the mc file. If you work with mc files, you must re-generate your .cf files based on the mc files using the m4 compiler.

Please see this thread, it may help you:

Thanks for all of your help....

I missed a line we had in the submit.cf file:

D{MTAHost}[mailhost.convergys.com]

added this, and restarted sendmail and mail is now being sent from server..
