For a project that I have been assigned to, I need to send emails to a business partner (business_partner.com) from one production server. However, my emails neither reach their destination nor bounce back to me.
Working with our business partner's IT support, the following error was discovered in their maillogs:
My IT support guys believe it is the cause of the problem. We created an alias but it made no change. Would adding my public internet email address to "trusted-users" file (we use sendmail) help?
How can I solve this?

Working with our business partner's IT support, the following error was discovered in their maillogs:
Further analysis by my IT support shows that emails are successfully sent out ("Message accepted for delivery"):chqsmt05 postfix/smtpd[1605]: NOQUEUE: reject: MAIL from unknown
[hidden_ip_address]: 450 4.1.8 <ddwmadm@pxclpd30.hidden_domain_name.com>: Sender address rejected: Domain not found;
from=<ddwmadm@pxclpd30.hidden_domain_name.com> proto=ESMTP helo=<pmempe31.prd.ext.hidden_domain_name.com>
The app I coded is not using a public internet email address (e.g. me@hidden_domain_name.com) to send these notifications. Instead, it uses an intranet email address (the server's where my code resides: user_name@servername.hidden_domain_name.com).[root@hidden_host_name log]# grep -i business_partner maillog*
