Hi, I am trying to send a mailing through CiviCRM, but when I try to send the test mail, I get the following error:

Failed to set sender: b.7.6.181373af205412c9@ [SMTP: Invalid response code received from SMTP server while sending email. This is often caused by a misconfiguration in Outbound Email settings. Please verify the settings at Administer CiviCRM >> Global Settings >> Outbound Email (SMTP). (code: 401, response: 4.1.7 Bad sender address syntax)]

I am able to send a test mail from the SMTP settings page. I also have an account for incoming mail set up with the same address than the "from" address.

Any idea where this can come from?

Thanks, Michael

I solved it by commenting out

if (!empty($headers['Return-Path'])) {
$from = $headers['Return-Path'];
}

in civicrm/packages/Mail/smtp.php, as suggested in:

FYI, I have exactly the same problem. Civicrm 4.5.0 on Wordpress 4.0. I'll try your workaround, thanks.
