When sending an email to the internet, MIME headers are not correct.

For example, sending a small image, the MIME headers for the attachment are like those:

Content-Type: attachment; name="Blue hills.jpg"
Content-Disposition: attachment; filename="Blue hills.jpg"
Content-Transfer-Encoding: base64


They should be:

Content-type: image/jpeg; name="Blue hills.jpg"
Content-disposition: attachment; filename="Blue hills.jpg"
Content-transfer-encoding: base64

Note the line "Content-Type:"

Some mail clients (if not all) cannot handle this and cannot open the attachment. See:

This is specially important to those trying to update their blog with some images.

Some more notes:

- Sending from WL2K to WL2K works OK
- Sending from the internet to WL2K works OK
- The problem shows with RMSE and Airmail and Paclink
- The headers are OK in the outgoing message within Airmail
- The headers are NOT OK in the outgoing message within RMSE
- The headers were OK before being sent to Paclink


Thanks for the good work.
