- Yes, IMAP2bis allows for transmission of the MIME structure of a message.
- However, IMAP2bis only helps for retrieving messages from a remote mailbox.
- What about local access to a mailbox? IMAP2bis clients can determine MIME
- structure without the entire text of a message, but what about the server?
- How can an IMAP2bis server efficiently store the MIME structure of a
- message so that client requests can be serviced quickly without additional
- parsing or large memory requirements?
-
- I agree that a sender should not generate and send a table of contents
- with a MIME message since, yes, that is redundant information. I am
- suggesting that efficient processing of MIME messages by the *receiver*
- would be facilitated by being able to store a TOC to speed up future
- accesses. Extracting MIME structure information can mean a large
- performance penalty due to the potentially large size of a MIME message.
- A TOC summarizes MIME structure information and makes it available
- efficiently since there is no longer a need to parse the entire note.
-
- There are many ways to implement a TOC; I'm curious and want to know
- if others have implemented a TOC mechanism or if there is some TOC
- standard/RFC I should look at. If not, I guess a TOC mechanism is
- something that can be considered private to a specific mail handler,
- and as such, can be implemented in any way.
-
- Thanks for the quick responses!
