There is quite a discrepancy in the rfc822.size reported by Dovecot and the actual space it takes up on my harddisk. I know there could be some overhead here from all the dovecot* and subscription list files in my imap folders, but like I stated in my email to the SquirrelMail plugin mailing list, about 1mb for a 4.3mb maildir mailbox might be a but much.
RFC822.SIZE reports message's "virtual size" as it is sent to IMAP clients, which means that if the maildir files contain LF-only linefeeds (which is usually the case), the RFC822.SIZE increases the size by the number of lines in the file (so each line ends with CRLF).
That however only increases the size reported by the Squirrelmail plugin. I don't know why it would report 1 MB less.
How does Squirrelmail plugin's INBOX usage compare with "du -sh cur new"? Do you have any files in tmp/ directories? Currently Dovecot never cleans up the tmp/ directory. I guess I should add the code for that..
