Choose a domain, a username, and a password on the next page. At the bottom of the page, click Create, and cPanel will create a new account.<\/p>\n\n\n\n
The next step is for your client to be configured so that it knows which server to connect to and how to authenticate. The necessary cPanel SMTP settings can be found in the Connect Devices interface.<\/p>\n\n\n\nThis page contains the username, URL, and SMTP port number of the outgoing server. These are the details you must provide to your app.<\/p>\n\n\n\nWe strongly advise you to use the more secure SSL\/TLS details instead of the insecure Non-SSL settings.<\/p>\n\n\n\n
<\/span>Troubleshooting Common SMTP Errors in cPanel<\/strong><\/span><\/h2>\n\n\n\nIf everything goes well, you can now send messages from your personalized address through your server. However, email is complicated, and misconfiguration is not uncommon to cause authentication or mail delivery issues.<\/p>\n\n\n\n
SMTP errors frequently manifest as undelivered messages. You attempt to send an email and receive a prompt response with an illegible error message and a number. The rest of this article will look at how you or your hosting provider can fix some of the most common errors.<\/p>\n\n\n\n
<\/span>Error 421 \u2013 Too Many Concurrent SMTP Connections<\/strong><\/span><\/h3>\n\n\n\nExim limits the number of concurrent SMTP connections it allows to avoid overloading the server, but on a busy server, the default cPanel setting of 100 concurrent connections may be insufficient.<\/p>\n\n\n\n
The “smtp accept max” directive in Exim’s configuration file controls the limit. In WHM, navigate to the Exim Configuration Manager under Service Configuration in the sidebar menu to change this value.<\/p>\n\n\n\nSearch for “smtp accept max” in the Advanced Editor tab. Increase the value, but keep in mind that too many SMTP connections may cause the mail server to run out of memory and crash.<\/p>\n\n\n\n
<\/span>Error 550 \u2013 Please Turn on SMTP Authentication in Your Mail Client<\/strong><\/span><\/h2>\n\n\n\nWhen your mail client sends messages, it must provide authentication credentials via a secure connection. Your server would quickly become a haven for spammers if anyone could connect and send messages, so the client must demonstrate that it is a legitimate sender for that account.<\/p>\n\n\n\n
When something goes wrong during the authentication process, you receive an Error 550 message. There are several possible causes for this error.<\/p>\n\n\n\n
<\/span>Misconfigured SMTP Client Authentication<\/strong><\/span><\/h2>\n\n\n\nError 550 is most commonly caused by either a misconfiguration in the email client or a client that is so old that it does not know how to establish a secure SMTP connection. If only one or a few users encounter the error, this is the most likely cause.<\/p>\n\n\n\n
The best way to resolve it is to use a modern client with the correct authentication information. If that isn’t possible, WHM includes a configuration change that allows SMTP connections from users who have previously authenticated using POP or IMAP, the protocols used to collect messages from the server.<\/p>\n\n\n\n
Navigate to the Tweak Settings interface, which is located in the WHM sidebar menu under Server Configuration. Look for “Pop-before-SMTP” and turn it on.<\/p>\n\n\n\n<\/span>Incorrect Email Routing for the Domain<\/strong><\/span><\/h2>\n\n\n\nIf someone receives a 550 error when attempting to send a message to an account hosted on your server, something is likely wrong with the domain’s routing configuration. This is usually because the domain is set up to use a remote mail exchanger rather than the one on your server.<\/p>\n\n\n\n
To ensure that emails for the domain use the local mail exchanger, navigate to DNS Functions > Edit MX Entry in the WHM sidebar menu. Select the appropriate domain and click Edit. Check that the Local Mail Exchanger option is selected.<\/p>\n\n\n\nAnother possibility is that the domain’s MX records are incorrectly configured. These are the DNS records that specify where a domain’s mail should be delivered. To see if they point to the correct IP address, use the “dig” command-line tool.<\/p>\n\n\n\nIn this example, we use dig to determine where our domain’s MX records point, and then we verify that the domain name record contains the expected IP address.<\/p>\n\n\n\n
<\/span>Take Control of Your Email with cPanel<\/strong><\/span><\/h2>\n\n\n\nEmail is critical to your brand’s identity and serves as a vital link between you and your customers and colleagues. When you host your own email, you have complete control over your brand and data.
