How to Choose the Correct Smtp Port in 2024

Have Trouble Determining Which Smtp Port to Use? I’ve Already Done That.

The email software you use to send emails, such as Apple Mail or Outlook, most likely also uses SMTP to upload your outbound emails to your mail server.

Additionally, using an SMTP port delivery service like Mailgun, SendGrid, or Google Workspace is one of the best methods to solve the issue of poor email deliverability on WordPress.

But if you attempt to configure SMTP with your email program or a WordPress website, you’ll undoubtedly run into the issue of choosing an SMTP port.

We’re going to go into all the SMTP port-related topics in this post to assist you in selecting the best SMTP port for your requirements

What does “SMTP port” mean?

Simple Mail Transfer Protocol, sometimes known as SMTP, is the accepted method for sending emails over the internet. Emails sent and received over the Internet are done so via mail servers.

For instance, your email client requires a way to upload the email to the outgoing mail server when you send it. The incoming mail server of the receiver must then be able to receive your email from the outgoing mail server.

Similar to website servers, mail servers also employ IP addresses for communication rather than a user-friendly front-facing domain name, such as 222.501.285.45.

An additional tool for facilitating computer communication, such as between two mail servers, is a “port”:

• A machine is identified by its IP address.
• A port indicates a particular program or service that is active on that machine, such as SMTP.

To make things a bit more relatable to people, here is an analogy:

The actual street address of a commercial complex is an IP address. A port is a particular company’s number inside that network of businesses.

If you need to send anything to that company, you can’t just address it to the corporate complex—you also need a mechanism to ensure it reaches the proper location inside the complex.

IANA, the body in charge of assigning IP addresses globally and performing other duties, is also in charge of registering port numbers for popular Internet services, like SMTP.

Your SMTP Port: Why Does It Matter?

You must specify both the IP address and the port number of an SMTP server in order to establish a connection (such as the Gmail SMTP Server). However, not all of the typical SMTP ports operate in every circumstance (more on this later). For instance, ISPs and cloud providers frequently block port 25, the standard SMTP port for transmitting messages between mail servers.

As a result, because so many services restrict port 25, you’ll frequently run into problems if you attempt to connect to an SMTP server over port 25.

What Port Should You Use for SMTP?

We briefly discussed this above, but because it’s crucial to make the appropriate choice, let’s go over it again.

You should nearly always utilize port 587 when setting up your WordPress website or email client to send emails using SMTP (submission). For submissions, this is the standard SMTP port, and it allows secure TLS delivery.

Port 2525 is a typical substitute if port 587 is banned for whatever reason. While most providers support and frequently utilize this port, it is not an official SMTP port.

Although many service providers still offer port 465 for SMTP, you should always attempt to utilize ports 587 and 2525 instead of port 465 as it is no longer a recognized standard.

Last but not least, even though port 25 is frequently used for SMTP relay, you shouldn’t use it while configuring a mail client or Wp site because the majority of ISPs and cloud hosting providers restrict port 25.

Conclusion

Emails are transported across the Internet in large part thanks to SMTP. You may set up your WordPress site to send emails over SMTP to increase the deliverability of transactional emails from your WordPress site. Furthermore, SMTP is used by email clients like Apple Mail and Outlook to transmit outgoing emails to mail servers. You must provide a specific SMTP port in order to connect your WordPress website or email client to the SMTP server.
