Fix dates via IMAP on messages

[Cody Baker]

I doubt there's anything out there automagically does it, but it 
wouldn't be terrible to write.  "In theory" (With huge sarcastic quotes 
around that) the e-mail dates follow the format described at 
http://www.w3.org/Protocols/rfc822/#z28 .   There's probably a lot of 
messages that deviate from that, but by in large you should be able to 
use them.  Just use a text processing language (like Perl), pull out the 
date field, and convert it into the format accepted by touch and modify 
the file date from that.  Recurse through all of the files and enjoy. 

Thank You,

The webmail client (no, this is not something I can change) relies on server-date for email dates, instead of looking at the email headers. The server-based date for the mail is of course the file creation/modification time, and cp -p was not used apparently.

Is there any program out there that will read the headers of the mail and change the server-date of the files? I've tried imapsync with -syncinternaldate, to see if it read headers, but it doesn't. I just want to be able to run the command on the user/imap server of choice, and have it read all the mail headers, and set the creation dates properly on the mails (all via IMAP).
