IT34275: ATTACHMENTS PROPAGATED OUT OF EMAILINPUT NODE MAY GET CORRUPTED.

APAR status

• Closed as program error.

Error description

• If you directly propagate an email with an attachment, received
  by the EmailInput node, to an EmailOutput node, the attachment
  is seen corrupted at the receiving end.
  

Local fix

• Using the following ESQL to explicitly set the attachment
  through the LocalEnvironment override makes it work.
  
  
  
  
  
  declare bl blob InputRoot.MIME.Parts.Part[2].Data.BLOB.BLOB;
  
  
  
   declare ctype Character
  InputRoot.MIME.Parts.Part[2].\"Content-Type\";
  
  
   set
  OutputLocalEnvironment.Destination.Email.Attachment.Content=
  bl;
  
  
   set
  OutputLocalEnvironment.Destination.Email.Attachment.ContentType=
  ctype;
  
  
   set OutputLocalEnvironment.Destination.Destination.Em
  ail.Attachment.ContentEncoding='Base64';
  
  
   -- Email Text
  
  
  
  Set OutputRoot.XMLNSC.MSG = 'Test Msg';
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All Users of IBM App Connect Enterprise 11.0 and IBM Integration
  Bus 10.0 using EmailInput node.
  
  
  Platforms affected:
  z/OS, MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  <span style="background-color:rgb(255, 255, 255)">If an email
  with attachments is directly propagated,  as received by the
  EmailInput node, to an EmailOutput node, then the attachments
  are seen </span><span style="background-color:rgb(255, 255,
  255)">corrupted at the receiving end.
  
  This issue occurs because EmailInput node does not retain base64
  form of attachments, for example, PDF documents..</span>
  

Problem conclusion

• A new environment variable with the name
  MQSI_EMAILINPUTNODE_PROPAGATE_BASE64_ATTACHMENT
  is introduced. The environment variable can be set to any value
  as below
  
  export <span style="background-color:rgb(255, 255,
  255)">MQSI_EMAILINPUTNODE_PROPAGATE_BASE64_ATTACHMENT=Y</span>
  
  When the environment variable is set, the EmailInput node will
  propagate every binary attachments in its original base64 form
  thus avoiding any corruption to the contents.
