What do the numbers in a multi-part email mean?
I was wondering what the follow means (the part between the text-only part and the html part of the email) and how I might calculate it for my own program to generate a multi-part email:
This is a multi-part message in MIME format. ------=_NextPart_32252.1057009685.31.001 Content-Type: multipart/alternative; boundary="----=_NextPart_32252.1057009685.31.002" Content-Description: Message in alternative text and HTML forms ------=_NextPart_32252.1057009685.31.002
(as seen here)
The rest of the message code makes sense to me for the post part.
