An Outgoing server port is a number, right after a server URL, for example,  highlighted 443 is a port address that opened under address and is separated by ‘:’

Why do we need a port?


To explain this thing, here, we know one server can have multiple addresses (IP), and basically, we have only one address attached to them. A server contains different services, such as website service, email service, File transfer services, etc.

So, how we can organize and differentiate them? We only have one address or we need to sort things out!

You got it. Yes by port, so we can separate our service by port address. That’s it. A single IP address can share my web services, and we can put many services under the same IP address, and separate them by PORT ADDRESS.


An Outgoing Port Address is provided by your mail service provider, where their mail server listens for outgoing email requests. For, example 465 is a port address of an outgoing mail server. For your reference, you can see this screenshot:
