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..
