Will be very 'nice' to have in IMAP functions one that allow to developer retrieve raw e-mail with all headers, parts, body ... . I work a lot with SMIME PKCS7 messages and I dream to have in our webmail feature to view source of e-mail (same as Outlook do). User in this case can see that his message encrypted and protected from anyone. Also it will be very useful for developers work with IMAP functions. For example, I spent a couple of hours to find out that object imap_fetchstructure in subtype always return TEXT/PLAIN (even if content type TEXT/HTML), if sender agent didn't specify MIME Version. If I had something like get raw e-mail I take a look on raw mails with 'broken' HTML mail and good one and resolve this problem quickly.

Thanks for attention and great product PHP,
