This isn't how I have it, I suppose Jack has a similar setup to mine,
I'll detail my setup:

First I have postfix installed with sasl/mysql backend, in MySQL I
have all the virtual accounts for various domains, for example I have
an entry for wael at nasreddine.com which states that it's a normail
Mailbox, not an alias it also guides postfix/courier-imap to the
folder where the e-mails are stored.

When you send an email to wael at nasreddine.com, it goes to the vmail
folder, Now using the package courier-imap which BTW provides both
IMAP and POP3 Server, the email received by postfix can be checked
using POP3 and the username wael at nasreddine.com (Full username because
this way I can have virtual domains, and the second most important
reason is below)

Now I have a normal UNIX user account 'wael' which has fetchmail that
downloads emails from many accounts, Gmail, Hotmail, Yahoo, and local
accounts (Which Jack mentioned as well and it's wael at nasreddine.com
for my case), fetchmail spits the mail out to procmail which do all
the filtering and deliver the email to /home/wael/.mail folder (If
you left the courier-imap config files as they are then you should
deliver to Mailfolder instead of .mail, check /usr/local/etc/courier-imap/*)

For the IMAP part, When I Use 'wael' instead of 'wael at nasreddine.com'
it doesn't use the vmail but the UNIX user instead (see below) so it
delivers whatever is under /home/wael/.mail :)

The trick is that courier-imap has authlib backend (authdaemon) , and
authlib has mysql/pam backends, so when u request mails for
wael at nasreddine.com it matches mysql qnd goes to virtual mail dir,
when you send wael it matches pam and so mail on home folder

If you need more assistance don't hesitate to ask...
