Hello, I'm using the SOAP API to create new mail_users. Creation is working great. However, I'm experiencing some differences between mail_users created via the SOAP API and mail_users created via the ISPConfig3 WebUI. Here's the process around the issue: Create new mail_user via SOAP API (code example below) Login using Squirrelmail as newly created mail_user Send an email `Sent` folder is empty This is unexpected. Expectation is that the sent email would be displayed here Create new mail_user via ISPConfig3 WebUI via Email -> new Email Mailbox Login using Squirrelmail as newly created mail_user Send an email `Sent` folder contains the newly sent email as expected In both scenarios, the sent email is delivered successfully to the intended recipient. Here is the code I'm using to create the new mail_user via the SOAP API: PHP: $client = new SoapClient(null, array('location' => $soap_location, 'uri' => $soap_uri, 'trace' => 1, 'exceptions' => 1)); $client_id = 1; $params = array( 'server_id' => 1, 'email' => '[email protected]', 'login' => '[email protected]', 'password' => 'bestpasswordever, 'quota' => 54200000, 'maildir' => '/var/vmail/mydomain.com/testuser', 'homedir' => '/var/vmail', 'cc' => 'email@example.com', 'sender_cc' => 'firstname.lastname@example.org', 'move_junk' => 'y', 'autoresponder_text' => NULL, 'autoresponder_subject' => 'Out of office reply', 'postfix' => 'y', 'access' => 'y', 'disableimap' => 'n', 'disabledeliver' => 'n', 'disablesmtp' => 'n', 'purge_trash_days' => 0, 'purge_junk_days' => 0, 'backup_interval' => 'none' );$mailuser_id = $client->mail_user_add($session_id, $client_id, $params); I'm not sure why the users created via the SOAP API are not getting messages moved in to the `Sent` folder. Is there a step I missed? Another API call I need to make? Something else?
