Sometimes after setting up an email client, you will be able to receive email but sending email will lead to an error message. There are many different possible causes to this problem including the email client settings and port blocking. One of the solutions listed below should help resolve your issue so that you can start sending email again.
If you are not able to send email, first make sure that you are using the correct email settings in your email client:
If you cannot send email, one possible cause is your ISP (Internet Service Provider) may have blocked Port 25 which is preventing your email from being sent. This feature can change without notice so if you previously were able to send email then this is the likely cause.
Here we have a few of the ISPs that have blocked Port 25, and their documentation related to the port being blocked:
The easiest way to find out if port 25 is blocking your email is to contact your ISP as they will be able to provide you with the information. For the advanced user, we've included directions below to test port 25 email blocking via the command line in Windows and Mac.
To test if port 25 is blocking your email, open your command line on your local computer. For windows users, you can access this via start -> run -> cmd. Mac users can use the "terminal" application. Once on the command line, type telnet yourdomain.com.com 25. Telnet is disabled in Windows Vista and Windows 7, so first you will have to enable Telnet. Visit the official Microsoft page for more information for enabling Telnet. If you get no response or a failure, port 25 blocking is the likely reason your email is not being sent.
If your ISP does block port 25, you can work around it in either of three ways:
As your ISP is blocking port 25, the best solution is to use the outgoing mail server provided by your ISP. To do this you would need to contact your ISP and ask what server they recommend.
In addition to using Port 25, our servers also use Port 587 to run SMTP. If 25 is blocked by your ISP, in your email client you can change 25 to 587 and see if you are able to send email.
You can also use the secure, or SSL, port for outgoing email. This will involve selecting the setting "this server requires a secure connection (ssl)" in your email client. Once you check that box, then change the email port listing from 25 to 465 and save the changes. These settings are usually found in the advanced settings of your email client. Please see the end of this article for more details.
You will also want to change the outgoing server name to secure##.webhostinghub.com, secure## being the secure alternative of the actual server you are on. For example, if your Welcome Email states that your account is on ehub23.webhostinghub.com, your outgoing server name should be secure23.webhostinghub.com. If you are unsure, please contact support.
In most email clients, the SMTP port and SSL settings are updated on the same settings page, and that page is generally in the advanced settings. The directions below will assist you in finding where to change these settings:
