In the past couple of days I did a PostFix/tls and courier-imap-ssl 
install.  I did not have these problems you are having though.  For my 2 
cents what I would check:

1)  #postfix check
This will check your config file and make sure it is ok.  I hope that 
this problem is caused by a simple typo and not something bigger.

2) #ps aux
See if postfix is actually running on your machine.

3) Now I am not going to say I know how POP works at all, I don't.  I 
know a bit more about the IMAP side of things.

In the following files I list what I changed in them:

/etc/courier/imapd
ADDRESS=0
PORT=143
IMAPDSTART=yes
MAILDIRPATH=Maildir

/etc/default/courier:
MAILDIR="Maildir"

/etc/postfix/master.cf
smtp      inet  n       -       -       -       -       smtpd -v


4)  just to be safe add them to your startup:
update-rc.d add postfix default
update-rc.d add courier-imap default
update-rc.d add courier-pop default

5) Just to be safe, make sure your DNS zone file has (Hopefully this can 
be moot)
yourdomain.com.   IN   MX   1   mail.yourdomain.com
mail.yourdomain.com.   IN   A   xxx.xxx.xxx.xxx

6) Open your window, call me to stand outside, take computer, throw it 
out the window.

Hope this helps.
