POP3/IMAP is not a function of postfix, sendmail or similar programs. It
is a function of programs like dovecot (in FC2/3).

To me able to have mail in a mail client as well as via a web browser,
you would set up an IMAP server on your server machine and let procmail
filter the messages into the users mail as they arrive.
You would then set up Squirrelmail so that your users can use mail
clinets residing on a client machine (Outlook, Thunderbird, Eudora,
etc.) as well as web browsers to log into Squirrelmail and read their
mail that way.

The mail server will not let you log in via pop - you need to configure
dovecot or similar program to do that.

your MTA (Mail Transport Agent), postfix, sendmail or similar handles
all incoming and outgoing mail traffic to and from your server. There is
no harm in setting up 2 servers, one for people to send out mail from
their desktop machines and one to receive mail (listening on port 25 for
SMTP traffic) from other sources over the net. However, unless you have
an extremely high load, there is no reason to do so.
If all your clients have Linux/UNIX machines, they can use that
machine's MTA to send out mail but usually not to receive mail.
POP is not an outgoing or incoming mail protocol as such. POP is
basically used to let mail clients download mail messages from the mail
