Adobe Campaign Classic: BatchEvents not delivered and processed by MTA

We are having problems sending Transactional PUSH notification BatchEvents when using SOAP calls.

All the messages are Ignored by Delivery (Status #11).

This issue only occours using the BatchEvent Service. For the same Registration token, on the same event and mobileApp it works using rtEvent

It looks like that MTA instance is not processing BatchEvents.

Are we forgetting some config tag on serverConf to make BatchEvents works correctly? Why MTA does't pick up my events?

Example call...

/nl/jsp/soaprouter.jsp

Header:

SOAPAction  ->  nms:batchEvent#PushEvents

Body:

<?xml version="1.0" encoding="UTF-8" ?>

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:nms:batchEvent">
