I think you maybe a little 'shocked and awed' by the plethora of possibilities. In my experience all you need to worry about is the MIME structure and make allowances for UU encoded attachments (there has to be exceptions, right?). MIME is described in rfcs 2045-2049 (2045 is the important one). If you want to produce the various parts of the email as sent then you'll need to handle TNEF, quoted-printable and base64. Things like Unicode, UPX, etc. are very much application details and shouldn't impact upon your email module - remember ClamAV handles these aspects itself. This is a little naive as a design document (TNEF is, strictly speaking from a MIME p-o-v, an application-specific problem) but hopefully it'll give you an idea of where to start. Think of MIME as describing a tree and you just want to decode (un-base64, un-quoted-printable, un-whatever) the leaves that interest you. I'm starting to think there may be some legs in producing XML from MIME for emails that flow through a process/work flow application - but that's definitely way OT. > <snip> > So, with that in mind, is there a document, or a group of documents > out there that I can read (gimme RFCs, non-official > standards, ANYTHING) > that describe the plethora of standards ClamAV uses or plans to use > in the future?

TNEF is (a bugger) and is described here : http://msdn.microsoft.com/library/default.asp?url=/library/en-us/mapi/html/_ mapi1book_tnef_stream_structure.asp. There are almost more things beside these to consider but I've not come across them yet. HTH, Dan. ------------------------------------------------------- This SF.Net email is sponsored by OSTG.
