Postfix on Intranet

Hello,

I have the setup of Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 9.04).

The situation is like this: I need only to work with a local domain (mail.company.local) for the employees send an receive email internally but they should not be able to send emails for an external domain (company.com), just local.

I played a little with some settings in main.cf but no success. I was still able to send emails to an account in yahoo.com from mail.company.local.

Could anyone help me pointing in what is the setting that would make this possible?

Thanks for your help

 

I believe if you mapped the following to local instead of smtp, then mails should no longer go to the outside world.

smtp unix - - - - - local
relay unix - - - - - local

Post your results.

Thanks,

Rocky

 

Hey Rocky,

Thanks for the help it worked. no email goes outside and all local gets delivered.

Now I have an extra question.

I added a line to main.cf to have a template for the mails bounced:

bounce_template_file = /etc/postfix/bounce.cf

For now all emails to the outside are staying in the queue, will postfix bounce it or delete it form queue and send back to the user an email with the bounce template? or I will ahve to do it manually? is there a way to not do it manually?

Thanks again for the help!

 

Happy to help you out. I know postfix will do whatever the default action is for non deliveries, but follow this link, it should clear up things for you a bit more:

Thank you once again
