> How are POP accounts different from system accounts?
POP accts are those stored on a remote mailbox from which you can
download mails to your hard disk using any mail client (from
Outlook to fetchmail/mutt)
> How do I setup POP accounts ( with access only to mailboxes and
> nothing else)?
On your linux server? Just limit permissions when setting up the
user acct. Block access to port 21, 23 etc and allow access only to
port 25 (smtp) and 110 (pop3). Better still - block port 25 also, so
that users must use their ISP's smtp server (vsnl say) to send mails.
Stick to the latest version of MTA (if sendmail, use 8.9.3 or 8.10
beta). If you dont want to use sendmail which is getting rather old
and insecure, there are other mail transport agents - iMail /
Exchange etc on windows / qmail etc on Linux.

There are several - Search for web based email scripts - these will
give a hotmail like interface to yr pop mailboxes, including the
facility to change passwords.
Also - if running a freemail or other service -
1. Ensure you are not an open relay smtp server (see
http://www.abuse.net/relay.html for more on this)
2. Maintain valid postmaster and abuse mailboxes (these may be
aliases to another account on your system - say webmaster or
whatever, no need to create separate accts)
3. Deal with complaints of spam etc promptly. If a user mentions
one of yr addresses in a spam mail (to make money reply to
[EMAIL PROTECTED] at once) then delete the guy's account at
once.
