mailx (sendmail) does not work

[John A. Hegedus_1]

While executing sendmail or mailx to try and email messages I get error Service Unavailable.
Do you know what would possibly cause this problem??? I've check all dns entries /hosts and .cf / .cw files.. Everything seems ok...I'm doing this from a new work station which coincedently is on the same subnet as my lap top... Other servers on diff subnets works fine

Have you configured the sendmail config file at all?

Do you have a Smart Relay defined?

How is the resolution working on your new work station? Is the DNS service defined?

Hi John,

You may be having anti-spamming configured on the mail relay. check the anti-spamming control on your system as well as the mail relay.

Do a

/usr/sbin/sendmail -v some_email_add@some_domain.com
your test here
.

this will give you the debug results which may help in identifying the problem.

Hope this helps.

I'd do a mod on Sanjay's command.

/usr/sbin/sendmail -v -d8.99 38.99 some_email_add@some_domain.com
your test here

.


The diagnostics will be more verbose.

looking at the /var/adm/syslog/mail.log
may prove useful as well.

Is your sendmail daemon runing ? this can be chacked with "ps -aef | grep sendmail".

Also depending upon the address where you are sending the e-mail, you may have to configure the /etc/mail/sendmail.cf or /etc/resolv.conf or /etc/nsswitch.conf file.

You can check if you are able to receive e-mails locally by -
sendmail -v root this will re-direct the containts of the /etc/hosts file to the mail box of root.
If this works, then there is some config. issue.

Upon investigation of /var/adm/syslog/mail.log the following errors show -----

return to sender insufficient permission relay=(completely qualified DNS entry) stat=Service unavailable
DSN: Service unavailable
I can ping the relay address no prob and the DS entry in the .cf file contains the right address???
