The library always enables ports and , but unless an Escalation user exists, there are no valid users that can log in to the WebLogic console. SNMP Ports. The library supports SNMP v3 protocol. E-mail Ports. The library can send e-mail messages when certain events occur see Configure Email Notifications.
If you configure e-mail destinations, you must also configure an SMTP server and open port DNS Ports. DNS configuration is optional. NTP Ports.

Computer ports are how individual computers connect to a network and complete electronic processes. An SMTP port is a combination of both: a port designed to send email through a network and to its recipient.
Of course, just as there are multiple computer ports, there are many SMTP ports that can be used. Request For Comments RFC was published, establishing port 25 as the default transmission channel for internet email.
However, the basis for SMTP connections remains the same or similar. In December of , R. Gellens and J. Klensin submitted RFC in support of adding a new specification for internet email communications. The RFC proposed a split of the traditional message submission and message relay concept. The RFC defined that message submission should occur over port to ensure new policy and security requirements don't interfere with the traditional relay traffic over message relay port SSL is commonly used for encrypting communications over the internet.
This command allows SMTP servers to communicate over existing ports by advertising whether the destination server supports TLS encryption. Mailgun supports TLS connections, which you can verify by connecting and issuing an "ehlo" from a command line interface.
You can test using the same command sequence on any SMTP server. Try Gmail or Yahoo, "telnet gmail-smtp-in. SMTP relaying is the transmission of email from email server to email server. It is traditionally blocked by residential ISPs and Cloud Hosting Providers, to curb the amount of spam that is relayed from compromised computers or servers. Unless you're specifically managing a mail server, you should have no traffic traversing this port on your computer or server.
However, because it was once recognized by IANA as valid, there may be legacy systems that are only capable of using this connection method. Typically, you will use this port only if your application demands it. A quick Google search, and you'll find many consumer Inbox Service Providers' ISPs articles that suggest port as the recommended setup.
However, we do not recommend it, as it is not RFC compliant. Instead, Mailgun provides it as an alternate port, which mirrors port , in the event the above ports are blocked. This port also supports TLS encryption. This is the default mail submission port. When users submit an email to be routed by a proper mail server, this is the one that will provide best results.
