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 ("reject: MAIL from unknown").
Further analysis by my IT support shows that emails are successfully sent out ("Message accepted for delivery").
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).
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?
Mmm...makes sense to me. I did not include snapshots of my maillogs but it seems to confirm with you stated. I believe sendmail can work with a smarthost. I'll look into it. – Chris – 2011-07-27T18:33:31.673
Accepted your answer. Although I could not vote it up since I have only 8 rep. – Chris – 2011-07-27T18:41:01.820
@Chris Thank you very much. I am maxed for today with upvotes anyway, so I only get the points for marking anyway, so that was great. I really appreciate it. – KCotreau – 2011-07-27T18:43:55.627
