Configuring the email parameters
To configure the email parameters:
1. Select Server Management > Control Panel. The “Service Settings” table
appears.
2. Click the green pencil icon next to Email Server. The “Email Parameters”
table appears; see Figure 62.
3. Fill in the fields in the “Email Parameters” table. The following paragraphs
explain these fields.
4. Click Save Changes in the “Email Parameters” table.
You can modify the following parameters:
• Maximum message size (MB)—It is important to enter a value here to limit
the size of incoming or outgoing email messages. If this field is blank, the
server will not limit the size of incoming messages, which may allow a
single message to fill up your available space on the hard disk drive. A
message that exceeds the specified quota of space on the hard disk drive is
returned to the sender as “undeliverable”. The default value is 5 MB; the
value must be a whole number greater than zero.
• Smart Relay Host Name—You can enter an optional host name in this
field. With this feature, you can configure the RaQ XTR to send Internet
email to a specific email server. Enter the host name of the email server
through which you want to relay your email.
This feature is useful if the RaQ XTR does not have direct Internet access
(for example, the RaQ XTR is subject to a restrictive firewall), but can
communicate with an email server that has direct Internet access.
• Check mail before SMTP relay—The RaQ XTR provides an option that
allows SMTP relay access for users based on previous POP authentication.
Click the check box to enable this feature.
• Relay for the following hosts/domains—You can specify a list of hosts for
which the SMTP server will relay email messages. You can enter
IP addresses or domain names in this field.
For more information, see “Email relaying” on page 140.
• Reject the following users/hosts/domains—In this field, enter email
addresses or domains from which you want to block any email. Anyone
trying to send you messages from one of these addresses or domains will
receive an error message in return.
