The POP3 service supports top-level and third-level domain names. For example,
example.com and mailserver.example.com are both supported.


Install SMTP Service (located under Application Server / IIS)
Install POP3 Service


The IIS SMTP configuration is an inbound / outbound configuration area very
similar to Exchange's Virtual SMTP Server. Here you can configure relay
restrictions, smart hosts, limits, etc...


The POP3 MMC is where domains and user mailboxes are created and managed.
Very few management options are available within this console if the
Encrypted Password File option is chosen, use the winpop.exe command line
utility to change passwords, etc.

When using the Encrypted Password File, POP3 logons are done using the full
email address as the username.


Windows Server 2003 POP3: Encrypted Password File
	Change User Password:
		winpop changepwd fernando@radio.local mynewpassword


Windows Help Files:
	ms-its:C:\WINDOWS\Help\cys.chm::/mail_server_role.htm


Configuring Mail Quotas (Encrypted Password File):
	winpop createquotafile username@domain [/user:username]
		o username@domain Specifies the user for which a quota file
		  should be created.
		o /user:username Specifies to use an existing user account's
		  quota file as a reference to create the quota file.

POP3 Quota Note:
	When a mailbox quota is exceeded, the user is not notified. E-mail
	intended for the user is not accepted, and a Non-Delivery Report (NDR),
	a notice that the e-mail was not delivered to the recipient, is returned
	to the sender.


Configuring Mail Quotas (Active Directory or Windows Accounts):

If you are using Active Directory integrated authentication or local Windows
accounts authentication, the e-mail delivered to a POP3 service mailbox will
have file ownership assigned to the mailbox user by default. A quota file is
created in the mailbox directory that contains the security identifier (SID)
of the user account associated with the mailbox. File ownership is then
assigned to the user account that corresponds to the SID contained in the
quota file. The SID is also used by the NTFS file system disk quota system
to enforce the quota limits specified on the user account matching the SID.
All e-mail transferred to the mailbox's mail store directory is marked with
the SID contained in the quota file; this marks the e-mail so it can be
monitored by the quota system.



POP3 Secure Password Authentication (SPA)

The POP3 service supports Secure Password Authentication (SPA) for Active
Directory integrated authentication and local Windows accounts authentication.
Secure Password Authentication requires that all e-mail clients transmit both
the user name and password using secure authentication. Secure Password
Authentication is more secure than the default of plaintext and, therefore,
is recommended over plaintext. Secure Password Authentication must be
configured on both the server on which e-mail services are running and on
every e-mail client that will connect to the mail server.
