Mail Adapter Change File Extension

Question

We have the receiver mail adapter setup to send the contents of a message to an internal email account. The adapter works and the message arrives as a soap.xml and payload.xml. The problem is that our mail system blocks the xml extension. Is there an easy way to switch the extensions from say xml to txt on the messages.
It looks like the PayloadSwapBean module can change the content type, but I just want to alter the extensions. I know I could use an XSLT to convert the contents to html and then just send the message as an html email but I was hoping to avoid design changes.
Regards

J,

<i>Q: Can I choose the name of an attachment in the mail?
           A: Yes. Most mail clients use some heuristics based on some MIME headers to derive the name of an attachment. The MIME headers involved in most heuristics are Content-Type, Content-Description, and Content-Disposition. When you create an XI message, the XI payload name is automatically set in the Content-Description. If you want to change or set all of these headers, you can use the MessageTransformBean module (Note 793922) in the adapter framework.

Q: How can I set the file name of a mail attachment?
            There are several MIME headers that play a role in how the client retrieves the file name of an attachment. Unfortunately, this behavior differs among various mail clients. The reason for this inconsistent behavior comes from the fact that this mechanism has been extended incrementally. The old way is to use the name parameter in the Content-Type header as specified in RFC1341. For example, you can set the content type of an XML attachment as:
           Content-Type: application/xml; name="abc.xml"
            RFC1521 discourages the use of this name parameter in anticipation of the new header Content-Disposition, which is defined in RFC1806.
            With this Content-Disposition header, you can set the file name as:
           Content-Disposition: attachment; filename="abc.xml"
            Some clients may show the Content-Description value as the file name. The Content-Description header is typically used to associate some descriptive information to an attachment (RFC1341) as in
           Content-Description: my xml file
            To avoid potential interpretation problems, it is recommended to combine the use of these headers.
How to use MailPackage in Receiver?
            A: When a mail message is sent out by the receiver adapter, normally the mail header information such as "From", "To", "Subject" are taken from the channel configuration. In order to dynamically set these headers, you can use the MailPackage mode. In this case, the XI payload must be formated in the Mail Package XML format. The format of this mail package XML document is defined in note 748024.</i>
Use the mail Package and the set the <b>Content-Disposition </b> with the file name and extension.
