postfix, maildir,spamassassin,pop,tmda,procmail,courrier imap,squirrelmail - HELP

Objective:

I would like to remotely access my linux email at home using the html squirrelmail along
with courrier Imap but at the same time be able read my mail using an Exchange client on Windows
using pop {at home}.


Current setup:

Currently running Postfix with procmail. Procmail passes the mail on to Spamassassin who
then passes it on to TMDA who then does local delivery. The current delivery is in /var/spool/mail/user.

ToDo:

1-tell TMDA to deliver mail to Maildir type format mail in /home/usr/Maildir.
2-install Courrier Imap and squirrelmail.
3-test squirrelmail using imap.

Question:

Is it possible to have a dual Maildir type setup using imap and html squirrelmail
AND
at the same time be able to use pop to read the Maildir directories ?

-Of course if POP is invoked first the mail will no longer be there {in Maildir}
to be read by the imap/squirrelmail team.

-Squirrelmail will be accessed via the web when I'm out of town.


Design: {sort of}

Postfix
v
procmail
v
spamassassin
v
TMDA
v
Local Maildir/ type directory -----------------> POP----------->Windozzz$/Exchange client
|

v
Courrier Imap------>squirrelmail

Ok, so , maybe I can change Exchange for IMAP access later... but I prefer not at this point...

THKS, for any help on this.
