PGP message parsing

I've just discovered that it is probably some of Microsoft Exchange infrastructure is encoding the header.

I also attached a message that can be used for test purposes.

The problem is not base64 and MailMate can handle that.

The problem is this part:

Content-Type: multipart/mixed;  
    boundary="_003_D1A05F2440914DEFAF7A082121B5C3A6isocorg_"
MIME-Version: 1.0

--_003_D1A05F2440914DEFAF7A082121B5C3A6isocorg_
Content-Type: text/plain; charset="us-ascii"


--_003_D1A05F2440914DEFAF7A082121B5C3A6isocorg_
Content-Type: application/pgp-encrypted;  
    name="PGPMIME Versions Identification"

1. It's multipart/mixed instead of multipart/encrypted.
   
2. There's a rogue body part (text/plain).

I'm not really sure what to do about this. I could probably work around number 1, but I'm not sure I should. Number 2 is a bit more tricky (implementation-wise) although MailMate already has the capability to indicate when a message has unencrypted subparts. The problem is that this is also against the standard -- in other words I'm not really sure I should work around it. At least not without warning the user. Do you often get this type of message?

Thanks,

I did overlook both those factions and misdiagnosed.

I do not consistently get these.

I think it has to do with the sending server that is being used. I think it may have something to do with the way that some servers on-path do content checking. I strongly suspect the office365 infrastructure mucking with the mime-encapsulation.

Apple's Mail does parse these messages. That doesn't really say you should, tough call.

I suggest you stall the ticket.
