Configuring services

Using the Web-based interface, you can manage and configure the network services that run on your hosting appliance. These services are:


Logging in as domain administrator
If you log in as a domain administrator, you can only configure services for Mail, and FTP. The other options are unavailable to domain administrators.

As a server administrator, you can configure these services even if your current login account doesn't permit you to use them. For example, your current login account may not grant you access to send and receive mail on the hosting appliance. But as a server administrator, you can still configure the mail service options by clicking Mail in the left menu.

To configure Web service
  1. In the left menu, click Web:

To configure mail service
  1. In the left menu, click Mail:
  2. Configure mail service settings as shown in the following table, then click Apply.

Option

Description

Smart relay hostname

The domain name of a smart host site for all outgoing mail (example: smarthostxyz.com). Instead of maintaining information about every user at this site on each host, you can maintain this information on one central host (the smart host). Any mail addressed to users that the local hosting appliance doesn't recognize is directed to the smart host.

Reject e-mail from unresolved hosts

When selected, this option checks the From field of an incoming message. If this option has a hostname that does not resolve to a valid IP address, the e-mail is rejected.

Enable Realtime Blackhole List (RBL)

When selected, this option tries to match the IP address of the e-mail sender against the "Realtime Blackhole List" (RBL). The RBL is a list of all known computers that send junk e-mail. If a match occurs, the e-mail is rejected. This option is not supported behind a restrictive firewall, because the appliance needs to connect to the RBL server.

Receive e-mail for hosts/domains (Aliases)

The e-mail hosts or domains on this appliance that should receive e-mail. Separate each entry with a semicolon, space, or comma (example: xyz-company.com;mycompany.com;).

Allow systems in these domains to send mail (Relay)

The e-mail hosts or domains on this appliance that should send e-mail. Separate each entry with a semicolon, space, or comma (example: xyz-company.com;mycompany.com;).

Reject e-mail from these users/hosts/domains

Rejects any mail messages that match a login name, hostname, or domain name in this this list. Separate each entry with a semicolon.

Maximum incoming message size

The maximum size allowed for incoming mail messages (including attachments). The maximum size can be set from 0 to 999 MB.

Maximum outgoing message size

The maximum size allowed for outgoing mail messages (including attachments). The maximum size can be set from 0 to 999 MB.
