Why Is My Port Closed After Forwarding? Simple Guide In 2022

Why is my port closed after forwarding? This article will tell you all about it.

Automatic port forwarding is the most preferred option as it is very easy to configure. In this article, we will discuss the reasons why your port is closed after forwarding emails.

Port forwarding is the process of forwarding your email to a new email address. But when we forward our emails it’s usually done using the SMTP (Simple Mail Transfer Protocol) protocol. This protocol is the most popular method used for email forwarding. It is because it is easier than other protocols and is more reliable than the others.

Forwarding email is one of the most useful features in Outlook but sometimes it gives an unexpected error and that is the most frustrating thing. So, I have shared with you some reasons why your port is closed after forwarding an email.

Port Closed After Forwarding: Reasons

1. The recipient has blocked your email:

If your recipient has blocked your email then it will not be able to forward your email to any other person. So, you need to check whether your recipient has blocked your email or not. 

2. The recipient is using a junk mail filter:

Junk mail filters are usually used by the recipients to stop the spam emails from entering their email. If you don’t want to receive any junk mail, then you need to unblock the sender from your junk mail filter.

3. Your recipient has turned on “delete” for all the forwarded emails:

If your recipient has set “delete” for all the emails that he/she has forwarded then it will delete the entire history of the forwarded emails and will make it impossible to recover that particular email.

4. Your recipient has blocked you from his/her contacts list:

If your recipient has blocked you from his/her contacts list then it will not be possible for him/her to forward your email to other people.

How Come My Port Is Closed After Forwarding?

Why Is My Port Closed After Forwarding?

An attack on a computer network involves an attacker trying to get into another computer system. The first line of defense for an enterprise or any other large network is usually a firewall.

Multiple Routers Are Connected

Incoming signals need to be sent from the first router to the second. The forwarding port rules are defined in router 2.

Incorrect IP Address

The port forwarding rule can cause a closed port if there is an incorrect address in it. If you want to send a connection, the address must be directed towards the computer you want to connect to.

Router’s Firewall Settings

It’s possible that you set all the rules correctly, but some of the rules do not allow open connections. If this is the case, you can either turn off the firewall completely or reduce the settings to the minimum security level.

Check The Mail Settings

Check the mail settings of your account and make sure that you have given the correct password. It is the most common reason that causes this issue.

Check The Email Client

It is very important to check the email client that you are using because some of the email clients don’t support the features of forwarding. You can use the Gmail app for Android to check the forwarding options.

Port Closed Due To Your Email Server

You may have forwarded your emails to the wrong email server and that is why your port is closed. You may also have a spam filter on your email server which is blocking your emails. So, it is better to remove that spam filter and check your email server settings.
