Note: If you configure your mail service to require CRAM-MD5, mail users’ accounts must
be set to use a Password Server that has CRAM-MD5 enabled.
To require SMTP authentication:
1 In Server Settings, click the Internet tab.
2 Click Mail Service and choose Configure Mail Service.
3 Click the Protocols tab and choose Apple Mail Service SMTP from the pop-up menu.
4 Click SMTP Options.
5 Select “Require authenticated SMTP using CRAM-MD5,” optionally select “Allow PLAIN and
LOGIN authentication,” and then click Save.
Sending SMTP Mail via Another Server
Rather than delivering outgoing mail directly to its various destinations, your SMTP mail
service can relay outgoing mail to another server. The other server then attempts to deliver
your SMTP service’s outgoing mail. Your SMTP service batches outgoing mail and sends it to
the other server, which acts as a proxy for delivering the mail.
m You may need to use this setting to deliver outgoing mail through a firewall set up by your
organization. In this case, your organization will designate a particular server for relaying
mail through the firewall.
m You may find this setting useful if your server has slow or intermittent connections to the
Internet, or if you are billed by the number of connections you initiate.
To relay SMTP mail through another server:
1 In Server Settings, click the Internet tab.
2 Click Mail Service and choose Configure Host Settings.
3 Click the Outgoing Mail tab.
4 Click “Relay all SMTP mail via” and enter the DNS name or IP address of the server that
provides SMTP relay.
5 Click Save.
Note: This option is disabled if the pop-up menu is set to “Limit to local users.”
Changing the SMTP Response Names
When your server connects with another server to send outgoing mail, your SMTP mail
service identifies itself by sending a name. Your SMTP service also sends its name when
another server contacts your server to deliver incoming mail. You can specify the name that
your SMTP service sends for incoming connections and the name it sends for outgoing
connections.
