ReadyNAS 3200 Software Manual
SMTP
The ReadyNAS 3200 device has a built-in e-mail message transfer agent (MTA) that is set up to
send alert e-mail messages from the device. Some corporate environments, however, might have a
firewall that blocks untrusted MTAs from sending out messages.
If you were unable to receive the test message from the Alerts Settings tab, it might have been
blocked by the firewall. In that case, specify an appropriate SMTP server in this tab.
Figure 2-26
If your firewall setting prevents alert messages from being sent by the embedded SMTP server, or
if your ISP blocks SMTP port 25, enter a remote SMTP server that alert email messages can be
routed through. Some SMTP servers will reject non-fully qualified histamines, so you may need to
change the hostname of this device to FQDN format in the Network tab (see "Hostname" on
page 2-6), i.e. use myhost.domain.com instead of myhost.
Internet Service Providers (ISPs) for home might also block untrusted MTAs. Furthermore, they
might allow you to specify their SMTP server but requires that you enter a user login and password
to send out e-mail—this is common with most DSL services. If this is the case, simply enter the
user name and password in the fields provided.
The TLS option allows the SMTP server and client to use transport-layer security to provide
private, authenticated communication over the Internet. This gives SMTP agents the ability to
protect some or all of their communications from eavesdroppers and attackers, and may be
required by the SMTP server you are using.
