A Chilkat email object can have attachments, related items, and attached messages. Attachments are file attachments that do not participate in the visual rendering of the email’s body. Related items are those images, style sheets, etc, that are embedded within the HTML body of an email and whose purpose is solely to be part of the visual rendering of the HTML. Attached messages are complete emails attached using the message/rfc822 content type.
Properties and methods for getting attachments include:
NumAttachments
SaveAttachedFile
SaveAllAttachments
SetAttachmentFilename
GetAttachmentData
GetAttachmentString
GetAttachmentStringCRLF
GetAttachmentSize
GetAttachmentHeader
GetAttachmentContentID
GetAttachmentContentType
GetAttachmentFilename
Properties and methods for related items include:
NumRelatedItems
GetRelatedContentID
GetRelatedContentType
GetRelatedData
GetRelatedFilename
GetRelatedString
GetRelatedStringCrLf
SaveRelatedItem
Properties and methods for attached messages include:
NumAttachedMessages
GetAttachedMessage
GetAttachedMessageFilename
An attached message contains the complete MIME source of another email (typically the original message in a reply or forward) embedded in a message/rfc822 MIME part. Some email clients construct forwards and replies by encapsulating the original email in a message/rfc822, some email clients do not. For example, Mozilla Thunderbird does not use message/rfc822 when constructing a reply or forward, whereas Yahoo Mail does. I ran a simple test to capture the MIME of a forwarded message from both email clients. You can examine it here and see the difference. (Note: I use a "chilkat_software@yahoo.com" email address, which is not checked. Please don’t send email to that address.)
This email was constructed by Yahoo Mail, and uses message/rfc822:
The embedded email is shown in boldface.
