Server relay is ignored if the FortiMail unit is operating in transparent mode, and “Use client-specified SMTP server to send email” (for outgoing connections) or “Use this domain’s SMTP server to deliver the mail” (for incoming connections containing outgoing email messages) is enabled. |
Server relay is ignored for email that matches an antispam or content profile where you have enabled “Deliver to alternate host”. |
GUI item | Description |
Name | Enter a descriptive name for this relay host. |
Host name/IP | Enter the domain name or IP address of an SMTP relay. |
Port | Enter the TCP port number on which the SMTP relay listens. This is typically provided by your Internet service provider (ISP). |
Use SMTPS | Enable to initiate SSL- and TLS-secured connections to the SMTP relay if it supports SSL/TLS. When disabled, SMTP connections from the FortiMail unit’s built-in MTA or proxy to the relay will occur as clear text, unencrypted. This option must be enabled to initiate SMTPS connections. |
Authentication Required | If the relay server requires use of the SMTP AUTH command, enable this option, click the arrow to expand the section and configure: • User name: Enter the name of the FortiMail unit’s account on the SMTP relay. • Password: Enter the password for the FortiMail unit’s user name. • Authentication type: Available SMTP authentication types include: • AUTO (automatically detect and use the most secure SMTP authentication type supported by the relay server) • PLAIN (provides an unencrypted, scrambled password) • LOGIN (provides an unencrypted, scrambled password) • DIGEST-MD5 (provides an encrypted hash of the password) • CRAM-MD5 (provides an encrypted hash of the password, with hash replay prevention, combined with a challenge and response mechanism) |
