hello, we have set up a centos 6 server.
on my dns entries the server's ip points to test.example.com

when i try to send an email from my server to my email user@example.com which it's on godaddy i get an error on the maillog user unknown but i am able to send emails to my gmail account.

when i do

sendmail -bv user@example.com
root... deliverable: mailer local, user root

sendmail -bv user@gmail.com
I will get deliverable: mailer esmtp, host gmail.com

So what I assume is that the sendmail is trying to deliver the emails to local accounts which they do not exist.

my /etc/hosts:

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.75 test test.example.com

How can I set up sendmail not to try to send on the local users???

If i dig mx example.com

I get the godaddy dns servers.

any ideas guys???

thanks

Add your domain to the relay_domains value in the main.cf file...

@OP
Remove example.com from /etc/mail/local-host-names and restart sendmail

@Kustom42
OP is talking about sendmail, not postfix

Regards

hello, the only thing i found on my local-host-names is the one below:


# local-host-names - include all aliases for your machine here.


also for another mail account on the example.com
i get the from the sendmail -bv
User Unknown....

Hi,

Check what's in /etc/mail/aliases (or /etc/aliases for some distros)

Regards

What's the vlaue of $HOSTNAME varibale ?. What you are getting hostname command ?

Also you can edit value in /etc/host.conf and make following entries

order bind,hosts

Thanks
