Hi,

I was very happy to discover CiviCRM and started right away reading some documentation.  The CiviMail and CiviEvent are perfect for our small organisation.  But unfortunately I've not been able to send some test messages to my SMTP server.  This is the full error I get :

**********************************************
The test mailing could not be delivered due to the following error:
Failed to add recipient: frank.melendez@yatri.be [SMTP: Invalid response code received from server (code: 553, response: 5.7.1 : Sender address rejected: not owned by user reply@yatri.be)]
**********************************************

I think the mail server of my provider (www.one.com) is checking the from address rather than the return-path.  How can I check this ?  Is there a way of debugging the communication between CiviMail and the SMTP server ?  Or maybe I could change a few things directly in the code to test a few values ?

Please help ... much appreciated for sure !

Regards,
Frank

Hi Donald,

Thanks for your answer.  I'll have a try with the code changes.  I've tried yor second suggestion already by providing a catch-all mail account but this doesn't work apparently.

Yes, I understand but that's exactly what's puzzeling me .... the errormessage doesn't state which address is represented by the 'Sender'.  The from address is configured as 'reply@yatri.be' and the return-path is also configured as 'reply@yatri.be'.  'reply@yatri.be' is a full account as opposed by an Alias.  So I'm really curious what our mailserver sees as 'Sender' ?
