No. See RFC2387 and RFC1873 In brief, the multipart/related MIME type exists so that a message can have multiple parts that refer to each other, most commonly used in the case of HTML messages with their inline images included as other parts of the message instead of referencing external sources. This works far better than multipart/mixed and hoping that the interpreter of the message understand the message itself as a sort of base 'directory' under which all the referenced images exist, especially given the problems of naming across platforms. A part of a multipart MIME message can have a Content-ID of the same form as a Message-ID, being (in theory) globally unique and made up of a domain part and a local part. A Message-ID form is a subset of the legal forms for e-mail addresses. The possible application of Content-ID's and cid: references to them is a lot broader than multipart/related messages with the main part being HTML and the others being images, but that is by far the most readily understood and most widely used application. -- Bill Cole [EMAIL PROTECTED] ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
