Cobalt RaQ 4 User Manual 55
You can modify the following parameters:
• Maximum message size (MB) It is important to enter a value here to limit
the size of incoming 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 4 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 4 does not have direct Internet access (for
example, the RaQ 4 is subject to a restrictive firewall), but can communicate
with an email server that has direct Internet access.
• Relay for the following hosts/domains You can specify a list of hosts for
which the SMTP server will relay email messages. For more information,
see “Email relaying” on page 56.
• Hosts/domains aliases In this field, enter all the IP addresses or domain
names of sites on which you receive email. You can only receive email that is
addressed to you on the domains specified here. For example, if you want to
receive email addressed to you at [e-mail], type
domain.com in this field.
You can also add email server aliases when creating a virtual site. For more
information, see “Overview of virtual sites” on page 41.
• 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.
