Wrong sys_userid in table spamfilter_users
When setting up an email-domain or an email account using the web client, the spamfilter "@domain" (respectively "account@domain"), the according SQL table entries (spamfilter_users) are assigned to admin (or the current user?) instead of the owner of the respective domain.
The expected behaviour would be to assign the table entries to the sys_userid of the client. This might be an issue when identifying table entries for cleaning up the SQL tables, e.g. when deleting the client.
