I am using Centos 5 on my server and when I try a test of sendmail

echo 'This is a test' | mail -s test-email todd@aristesoftware.com

I get the following lines in maillog:

Aug 20 10:26:14 localhost sendmail[14452]: r7KHQ6Rx014450: to=<todd@aristesoftware.com>, ctladdr=<root@localhost.localdomain> (0/0), delay=00:00:08, xdelay=00:00:08, mailer=esmtp, pri=120369, relay=mailin-02.mx.sonic.net. [69.12.208.76], dsn=5.0.0, stat=Service unavailable

Aug 20 10:26:14 localhost sendmail[14452]: r7KHQ6Rx014450: r7KHQERx014452: DSN: Service unavailable

Aug 20 10:26:14 localhost sendmail[14452]: r7KHQERx014452: to=<root@localhost.localdomain>, delay=00:00:00, xdelay=00:00:00, mailer=local, pri=31627, dsn=2.0.0, stat=Sent

I am not a Linux guru...especially about sendmail. Is there a place in the config file for sendmail where I should enter the IP of server provided by my ISP?

With appreciation...

Todd

Use a domain name that resolves properly on the 'net?

Are you allowed to relay through mailin-02.mx.sonic.net. ?

I agree with this also.

BTW you can answer that question yourself if you

I did some researching on setting up sendmail so that it will relay to my ISP, however my ISP uses port 587 with "Password, transmitted insecurely". I do not believe my setup included the port setting or specified the type of authorization. Is this something simple in either the access file and/or the sendmail.mc file?

Here is my access file setting:

# Check the /usr/share/doc/sendmail/README.cf file for a description
# of the format of this file. (search for access_db in that file)
# The /usr/share/doc/sendmail/README.cf is part of the sendmail-doc
# package.
#
# by default we allow relaying from localhost...
# Connect:localhost.localdomain RELAY
# Connect:localhost RELAY
# Connect:127.0.0.1 RELAY

AuthInfo:mail.sonic.net "U:my_user_name" "P:my_password"

And I just changed this line in sendmail.mc:

dnl #
define(`SMART_HOST', `mail.sonic.net')dnl
dnl #

The maillog gives these lines for my test message:

Use a domain name that resolves properly on the 'net?

I am not sure what to put into ctladdr=<root@localhost.localdomain>. The address of the sender (me) is

todd@aristesoftware.com

My local server is www.toddcary.com while my domain name on my ISP's server is aristesoftware.com

Needless to say, I am confused about what to change and where.

What parameter in which file should be modified?

Todd

No, you're not. You're sending email as "root@localhost.localdomain". Your domain name may be toddcary.com or aristesoftware.com but not both as they currently point to separate IP addresses.


When Sendmail (or any MTA) starts up it tries to determine the fully qualified domain (FQDN) name by reading /etc/hosts and your server is known as "localhost" or "localhost.localdomain" in full. What you need is to do is enable the MTA to resolve the IP address b****9.b****e.com resolves to to www.toddcary.com in /etc/hosts.

Thank you for your patience. My Centos server has been running for years as a place to test my website development, so outside of doing backups and minor file maintenance, I NEVER have to touch the server (wish I could say that about Windows). Now I am doing some work with Concrete5 that requires sendmail (my mail object in php gets me by otherwise).

So, here is my hosts file:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
127.0.0.1 localhost.localdomain localhost centos5

What line should I add to it? My IP is 216.228.174.9 .

With appreciation...

Todd

P.S. What does the ::1 mean?

Just in case these entries in the sendmail.mc could have an adverse effect, here they are

define(`SMART_HOST', `mail.sonic.net')dnl
LOCAL_DOMAIN(`localhost.localdomain')dnl
MASQUERADE_AS(`toddcary.com')dnl
MASQUERADE_DOMAIN(`toddcary.com')dnl
FEATURE(masquerade_entire_domain)dnl
FEATURE(masquerade_envelope)dnl

Todd

Sorry for the late reply.

SMTP traditionally uses port TCP/25. The MSA uses port TCP/587, see http://en.wikipedia.org/wiki/Mail_submission_agent for a short intro (and reason why your ISP should adhere to RFCs and allow port TCP/25) and /etc/mail/submit.mc for local config (which you never should have to change anyway) and if you would want to verify open ports: 'pgrep sendmail | xargs -iX lsof -Pwlnp 'X' -a -i;'.


No idea where this should go.


Often restarting Sendmail would be enough but if and when you edit .mc files please ensure the corresponding .cf gets rebuilt.


After fixing your 'root@localdomain' issue this should be the next one to work on.


When Sendmail starts up it tries to determine the fully qualified domain (FQDN) name by reading /etc/hosts. If you MASQUERADE_AS(`www.toddcary.com')dnl then add the correct IP + host name entry for www.toddcary.com in /etc/hosts and restart Sendmail.

What is the correct syntax for adding "...then add the correct IP + host name entry for www.toddcary.com in /etc/hosts and restart Sendmail." to hosts?

Todd

Just like the rest of the file. One IP address, one or more tabs or spaces, one fully qualified domain name, one or more tabs or spaces, one alias, one return.
shows "^I" for tabs and displays $ at end of each line.

I believe I am missing something in the hosts file syntax:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
127.0.0.1 localhost.localdomain localhost centos5
216.228.174.9 toddcary.com localhost

sendmail log file after restarting sendmail:

hosts file looks OK but
points to another type of error. Just a hunch but check if the same happens with sending email as unprivileged user?
