Postfix: aliases error

[ciprianmk]

Hi,

I'm new using postfix, and i have a problem using aliasses.

I have setup a few aliases, and when someone from outside the server want to send mail to one of the aliases he receives back an Undelivered Mail Returned to Sender email.

I have changed the address with example.

This is the email that users receive:

The mail system

<address1@example.com> (expanded from <hq@example2.com>):
host
relais-ias89.example3.com[193.X.X.X] said: 554 5.7.1
<address2@example.com>: Sender address rejected: domain
use is
reserved (in reply to MAIL FROM command)

<address1@example.com> (expanded from <hq@example2.com>):
host
relais-ias89.example3.com[193.X.X.X] said: 554 5.7.1
<address2@example.com>: Sender address rejected: domain
use is
reserved (in reply to MAIL FROM command)


And this is the Delivery report


Reporting-MTA: dns; example2.com
X-Postfix-Queue-ID: XXXXXXXXXXx
X-Postfix-Sender: rfc822; address2@example.com

I want to mention that i am not using any access list or any domain list.

Thank's a lot

Please check if the MX record of your domain is pointing to the correct server. You can check that as follows:

dig mx yourdomain.com

If you are sure that it is correct, please check your mail log for errors.

Are there any errors in your mail log (in the /var/log/ directory)?

Hi,

i have looked for any errors but there aren't.
the problem is that he receives the message in the first post, but the email send to that alias is received by the addresses which are part from that alias.
