What are the commonly encountered email sending problems?

It is very possible, when configuring your email on your software, that you will encounter certain errors that prevent you from sending emails.

Indeed, the commonly encountered errors are as follows:

• A configuration problem with your software
• Filtering at the level of your network and your provider, preventing you from using the SMTP port

To diagnose the problem encountered, the first thing to do is to check the configuration of your email client. Indeed, it is possible that you made an error when configuring it, which prevents you from connecting to your SMTP server to send email.

Checking authentication activation

The first thing to check is that authentication is enabled on your email client. Most software includes a checkbox labeled "my server requires authentication". This is the case for the Outlook email client.

It is also necessary to check that the box "use the same settings as the incoming server" is checked. Indeed, most software asks you to configure the information on the incoming server (IMAP). If this box is not checked, you will not be able to authenticate on the outgoing server in order to send a message.

Checking the connection ports 

You will then need to check the sending ports, which are as follows:

• 465: This is the default port for using the SMTP server. To use this port, the "SSL/TLS encrypted connection" box must be checked.
• 587: This is the default port for using the SMTP server. However, to use this port, you must use an unencrypted connection.

Checking the host name

The last parameter to check is the host server name. Indeed, your host server name must be mail.domain.com (Domain.com must be replaced with your domain). You can also use domain.com if you wish or the IP address of your cPanel shared hosting. If you are using an SSL/TLS connection, you will first need to activate the SSL certificate on your domain name. Indeed, if SSL is not enabled, you may encounter the error "Invalid SSL certificate".

You can check and use the following help to configure your software:

• What is the difference between an SSL/TLS connection and a non-SSL/TLS connection?

Conclusion

You are now able to troubleshoot your email client for your cPanel shared hosting whenever an error occurs when sending messages. Indeed, it is necessary first to check that the configuration you are using is correct. If not, change it.
