What is a Part.001 file attachment and what is the fix for it What is a Part.001 file attachment and what is the fix for it philswan (TechnicalUser) (OP) 29 Dec 00 04:23 I need an in depth explanation of what causes a attachment to be converted to part.001 and is there a fix for it.Thanks RE: What is a Part.001 file attachment and what is the fix for it rjs (MIS) 2 Jan 01 14:30 From Novell's knowledgebase:An attachment with a name PART.001 means the SMTP/MIME gateway did not understand part of the MIME message. MIME messages are split into parts using a boundary definition to separate each of the parts. Within each part are instructions to identify the type of part being read. If the gateway does not understand a part of the message, the unknown part will be clipped out of the message and attached as an attachment with the generic name PART.001. Each additional unknown part will be given the incremented name PART.001, PART.002, PART.003, etc.There could be several reasons why a message part is unknown:1. The content-type is multipart/appledouble. Until SMTP2.EXE (gateway code prior to 4/18/97), this was an unsupported content type. 2. The message is sent from Microsoft Exchange in "Microsoft Exchange Rich Text Format." This is not supported by the GroupWise Gateway. 3. The CheckPoint FireWall-1 inserts a blank line within an UUENCODED attachment. This bug in the firewall software causes the gateway's UUDECODE to fail.4. The attachment header is missing the Content-Disposition line. The Content-Disposition line followed by a blank line should immediately precede the attachment.
