   • SMTP.
   • LMTP.
8. In the Host field, enter an IPv4 address (for example, 192.168.0.1), an IPv6 address (for example, 2607:f0d0:1002:51::4), a FQDN, or a domain name to which you want to configure mail routing.
9. In the Port field, enter the port you want to use for connecting to the server to which you want to route email.

11. If you are adding a domain or subdomains, in the TLS Encryption mode for outgoing mail settings group, select one of the following options:
    • Use <mode configured in the TLS encryption section> if for all outgoing messages to this domain or subdomain, you want to use the TLS connection encryption mode that is set for all of the mail server's outgoing messages.
    • Override TLS Encryption mode for this domain if you want to configure a different connection TLS encryption mode for outgoing messages to this domain or subdomain.
12. If you have chosen an alternative TLS encryption mode for this domain or subdomain, in the drop-down list below, select the TLS encryption mode that you want to set for the connection.
    • No TLS Encryption.
