I'm a big fan of keeping MIME-messages bit for bit like they are. I still use Ex2k3 and I love the STM-database which was removed.
I think that Exchange must be able to give out an mime mail the same way it was stored in it. e.g. if I do a IMAP append I want to get that mail back. Of course:
- With ALL x-headers
- With the same mime boundaries
- With the same amount of characters in base64 encoded attachment
- Not chaning QP with base64
- Same wordrapping in headers
- With no change to HTML content, e.g. removing comments
- With the ability to fix bad stored encoding/charset
- If there is a plaintext part and a html part, they shall be preserved (some webmailer from gmx.de forwarded a mail to me and I was in the transition of mails. The version Outlooks integrated pop3-client pulled was destroyed!!! The forwarded part was gone. The version stored on a unix system was fine)
- If a mail is broken or spam, I want to be able to view the source and analyze it.
- If it is a NDR with parts of the original mail attached, I must be able to see the original mail, e.g. if I was not the person who sent the mail. It might be spam I want to investigate or something I was not supposed to see and of course I must be able to see such stuff
I understand that whenever I move the mail using Outlook, it will be destroyed. Everything that goes to a PST or with exmerge will be destroyed forever (like lost adresses).
I still don't understand anything about how Exhange 2007 would be able to preserve mime messages at least a bit using the new design without stm.
Is every HTML mail converted to RTF with some embedded markers for html-comments?
Well, I would appreciate any pointers to answers to these questions, information about removal of stm from e2k7 and about imail is very limited.
BUT: Does your posting mean that X-headers are destroyed??? As admin I must be able to see such stuff if I need it. Will I be at least able to use IMAP to go into the mailbox and fetch the mail with all x-headers??
