Configuring Receiver mail adapter with dynamic email addresses

Question

Hi,
I'm a newbie to XI and I have problems in configuring the Receiver mail adapter with the "Use Mail package" option selected. I am trying pickup a file (using file adapter on Sender side, picks up a simple XML file) and after mapping in XI, send the message as an email message to dynamic email addresses.
Everything works fine if I did not select the "Use Mail Package". But when I choose that option it errors out. I followed this blog posted on SDN -
/people/michal.krawczyk2/blog/2005/03/07/mail-adapter-xi--how-to-implement-dynamic-mail-address
The following XML message is my source
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/Somenamespace">
   <ns0:Message1>
      <ns1:studentlisttest xmlns:ns1="urn:karthiksender_to_karthikreceiver">
         <Student>
            <studentid>1</studentid>
            <lastname>Studentlastname</lastname>
            <firstname>Studentfirstname</firstname>
         </Student>
         <Mail>
            <From>[email protected]</From>
            <To>[email protected]</To>
            <Subject>Test mail adapter</Subject>
         </Mail>
      </ns1:studentlisttest>
   </ns0:Message1>
</ns0:Messages>
What I want to accomplish is, I have a simple message mapping where the Studentdetails are mapped to, lets say Customer details. For convenience lets keep it simple, StudentId --> Customerid, (student)Firstname --> (customer)Firstname, (Student)Lastname --> (customer)Lastname
I would like to get the Customer details as an XML attachment or in the body of an email with from, to and subject corresponding to that specified in the <Mail> node.
I followed the instructions posted on the blog and it works fine if I don't map the studentdetails to customerdetails. I did multimapping, with one source message (the xml file I posted above) and two target messages (customerdetails and Mail, which is the external definition posted on the blog). I beleive I'm missing something here. Could somebody please guide me through this?
Thanks

hi,
I still have not found the solution for this problem. Michal, your blog works fine when my source message has got only the mail details. As per your advice, I tried modified the structure of the xsd file as follows
<xs:schema targetNamespace="http://sap.com/xi/XI/Mail/30"
  xmlns:xi="http://sap.com/xi/XI/Mail/30"
  xmlns:xs="http://www.w3.org/2001/XMLSchema">
<!--
Mail
  -->
  <xs:element name="Mail">
    <xs:annotation>
      <xs:documentation>Mail package for XI - Mail Adapter</xs:documentation>
    </xs:annotation>
    <xs:complexType>
      <xs:sequence>
        <xs:element name="Subject" type="xs:string" minOccurs="0"/>
        <xs:element name="From" type="xs:string" minOccurs="0"/>
        <xs:element name="To" type="xs:string" minOccurs="0"/>
        <xs:element name="Reply_To" type="xs:string" minOccurs="0"/>
        <xs:element name="Content_Type" type="xs:string" minOccurs="0"/>
        <xs:element name="Date" type="xs:dateTime" minOccurs="0"/>
        <xs:element name="Message_ID" type="xs:string" minOccurs="0"/>
        <xs:element name="X_Mailer" type="xs:string" minOccurs="0"/>
        <xs:element name="Content" minOccurs="0">

          </xs:annotation>
        </xs:element>
      </xs:sequence>
      <xs:attribute name="encoding" type="xs:string"/>
    </xs:complexType>
  </xs:element>
  <xs:element name="MailReceipt">

    <xs:complexType>
      <xs:sequence>
        <xs:element name="Server" type="xs:string"/>
        <xs:element name="Format" type="xs:string"/>
        <xs:element name="UseMailPackage" type="xs:boolean"/>
        <xs:element name="Encoding" type="xs:string"/>
        <xs:element name="Subject" type="xs:string" minOccurs="0"/>
        <xs:element name="From" type="xs:dateTime" minOccurs="0"/>
        <xs:element name="To" type="xs:string" minOccurs="0"/>
        <xs:element name="Date" type="xs:dateTime" minOccurs="0"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
  <xs:element name="CustomerlistExternal">
    <xs:annotation>
      <xs:documentation>Customer List</xs:documentation>
    </xs:annotation>
    <xs:complexType>
      <xs:sequence>
        <xs:element name="Customername" type="xs:string"/>
        <xs:element name="Customerid" type="xs:string"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>
My source message will be something like
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
   <ns0:Message1>
      <ns1:studentlisttest xmlns:ns1="urn:karthiksender_to_karthikreceiver">
         <Student>
            <studentid>1</studentid>
            <lastname>abclname</lastname>
            <firstname>abcfname</firstname>
         </Student>
         <Mail>
            <From>[email protected]</From>
            <To>[email protected]</To>
            <Subject>Testing Mail adapter</Subject>
         </Mail>
      </ns1:studentlisttest>
   </ns0:Message1>
</ns0:Messages>
I have mapped the <student></student> information to customerlist, with customerid --> studentid and customername --> firstname or lastname (for symplicity). This was a multimapping with one source and two target messages. My test mapping output is
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
     <ns0:Message1>
          <ns2:Mail xmlns:ns2="http://sap.com/xi/XI/Mail/30">
               <Subject>Testing Mail adapter</Subject>
               <From>[email protected]</From>
               <To>[email protected]</To>
          </ns2:Mail>
     </ns0:Message1>
     <ns0:Message2>
          <ns2:CustomerlistExternal xmlns:ns2="http://sap.com/xi/XI/Mail/30">
               <Customername>abclname</Customername>
               <Customerid>1</Customerid>
          </ns2:CustomerlistExternal>
     </ns0:Message2>
</ns0:Messages>
So how would I get this part of the <CustomerlistExternal></CustomerlistExternal> part of the message as an attachment to the mail address specified in the <ns2:Mail></ns2:Mail> tags.
I'm definitely not understanding it right and am missing something. Could you give me step by step instructions to acheive this. I apologize for the trouble..this would be of great help to me.
Thanks
Karthik
