Setting dynamic attachment name in mail adapter

Question

Hi experts,
I have a mail adapter that send e-mails from ECC to several address.
I have configured dynamically the FROM and TO field using the code showed below in message mapping:
public String SetMailParameters(String Mail_address_to, Container container){
   //write your code here
  String valueFrom = "my_address";
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key1 = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/Mail",  "THeaderFROM");
DynamicConfigurationKey key2 = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/Mail",  "THeaderTO");
conf.put(key1, valueFrom);
conf.put(key2, Mail_address_to);
  return  "";
In communication channel I have checked ASMA and variable transport binding (using XHeaderName1 and 2), mail package is not checked.
It works fine!
My question is:
I need to dynamically configure also the Attachment name: is it possible?
I've tried adding the code below:
DynamicConfigurationKey key3 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
conf.put(key3,Attachment_name);
and also
Transform.ContentDisposition      attachment;filename=<FileName>
in Message TransformBean in communication channel, but it doesn't work!!!
Any idea?
Thanks

Hi,
thanks a lot!!
ASMA and variable transport binding must be checked or not?
it raise an error in runtime workbench message monitoring:
2010-09-02 17:41:15 Success Mail: calling the adpter for processing

This is my message in message monitoring:
<?xml version="1.0" encoding="UTF-8" ?>
- <ns1:Mail xmlns:ns1="http://sap.com/xi/XI/Mail/30">
  <Content_Disposition>"attachment; filename="MyFileName.txt"</Content_Disposition>
  <Content>ZLF;0001000079;Dealer Motors UK</Content>
  </ns1:Mail>
In message mapping with target message mail package I've linked Content_Disposition with the constant
"attachment; filename="MyFileName.txt"
If I cancel this relation the mail arrives correctly.
One other thing: when I took mail.xsd from SAP the fields Content_Disposition and Content_Description weren't in, so I added them manually in XSD.
thanks
