Hi Alberto,

Thanks for the examples.

My view is that the server through which your mail passes
disassembles the message and then doesn't reconstruct it
again properly, but instead creates a broken format.

Look at the format:

-------8<-----8<------8<-----8<------8<-----8<------

--MP_/jAtc4e_nBB65zIUi=IePqMb
Content-Type: text/plain

Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename=prova.xyz

--MP_/jAtc4e_nBB65zIUi=IePqMb--

------->8----->8------>8----->8------>8----->8------

Note the blank line between Content-Type and
Content-Transfer-Encoding. This is wrong, and is not written that way
by Claws Mail.

You can probably verify this by saving your sent mail and checking
the saved mail.

with regards

Paul
