Hello there!
Thank you for the help, after removing the password field, it did work ...
To set a password, should it then be done afterwards in another API call or?
I'm trying to create a mailbox by using the XML api with the following code:
<?xml version="1.0" encoding="UTF-8"?>
<packet>
<mail>
<create>
<filter>
<site-id>12</site-id>
<mailname>
<name>testing</name>
<mailbox>...
