http://en.wikipedia.org/wiki/Maildir
Maildir is a format for an e-mail spool that does not require
file locking to maintain message integrity because the messages
are kept in separate files with unique names.

Wrong tool. fetchmail's only function is to, well, fetch mail
from a POP server and then pass it along to another process in
your system. Usually an MTA, procmail or /var/mail/$USER.

Description: archive and compress your old email
Archivemail moves old mail out of a mailbox (in Maildir, MH,
or mbox format, or via IMAP) and archives it in a compressed
mbox-format mailbox file. It is well suited to be run from cron
for automatic archiving of your old mail.
If you don't want your old mail compressed into mbox.gz files,
take the source code and modify it to do what you want.

We've told you already times: fetchmail, exim4|postfix, spamassassin,
maildrop|procmail and Maildir. Then access your mail from a *locally
running* IMAP server.
