Port 25 blocking<\/h2>\n

If you cannot send mail, the problem is likely a restriction by your ISP (Internet Service Provider) as many block the normal sendmail port 25<\/strong>, due to their own security concerns. This can be the case even if sending was working recently as some ISP\u2019s roll these changes through without warning.<\/p>\n


\nChecking if Port 25 is blocked<\/span><\/p>\n

For the average user, the easiest way to find out if port 25<\/strong> is being blocked is to contact your ISP and ask them. For the advanced user, we\u2019ve included directions below to test port 25<\/strong> blocking via Telnet<\/a> and the command-line interface.<\/p>\n

To test if port 25<\/strong> is blocked, open your command line on your local computer. For windows users, you can access this via start > run > cmd<\/strong>. Mac users can use the \u201cTerminal<\/em>\u201d application. Once on the command line, type: (Note! Be sure that you replace example.com with your actual domain name)<\/p>\n

telnet example.com 25<\/pre>\n
Please note:<\/strong> Telnet is disabled on newer versions of Microsoft Windows. If you receive an error similar to,\u201dWindows cannot find \u2018telnet<\/em>\u2018\u201d, you may need to enable telnet. Please see our article on Enabling telnet on a Windows computer<\/a><\/p>\n
If you get no response or a failure, port 25<\/strong> blocking is the likely issue. It is NOT port 25<\/strong> blocking if you receive a response similar to this:<\/p>\n
220-servername.inmotionhosting.com 220-We do not authorize the use of this system to transport unsolicited, 220 and\/or bulk e-mail.<\/pre>\n
Port 25 blocking \u2013 Fixes<\/h2>\n
If your ISP does block port 25<\/strong>, you can work around it in one of three ways:<\/p>\n
The Preferred Solution<\/b><\/h3>\n
As your ISP is blocking port 25<\/strong>, the preferred solution is to use the outgoing mail server provided by your ISP. As each Internet Service Provider has different settings you will need to use (such as username and password, smtp server\u2026), you will need to contact your ISP for the correct settings. We do have alternate solutions to this which involve going over port 465<\/strong> or 587<\/strong> instead of 25<\/strong>, however if your ISP begins to block 465<\/strong> or 587<\/strong> in the future, you will once again be unable to send email.<\/p>\n
Alternative Solution #1<\/h4>\n
Beginning in late March 2010, we are updating many of our servers to run SMTP over port 587<\/strong> as well as port 25<\/strong>. If your ISP is blocking port 25, simply change your SMTP port number to 587.<\/strong> This setting is usually found in the advanced settings of your email client. Please see the end of this article for more details.<\/p>\n
Alternative Solution #2<\/h4>\n
Use the secure<\/strong>, or SSL, port for outgoing mail. This will involve selecting the setting \u201cthis server requires a secure connection (SSL)<\/em>\u201d in your mail program. You only need to make this change for the outgoing mail server. Once you check that box, then change the port listing from 25<\/strong> to 465<\/strong> 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.<\/p>\n
You will also want to change the outgoing server name to secure##.inmotionhosting.com<\/em>, secure## being the secure alternative of the actual server you are on. For example, if your Welcome Email states that your account is on biz54.inmotionhosting.com<\/em>, your outgoing server name should be secure54.inmotionhosting.com<\/em>.<\/p>\n
If you are unsure, please contact our live tech support team<\/a>. This option will work in most cases, however we cannot guarantee that your internet service provider will not some day in the future begin to block port 465<\/strong>. Below are instructions to change the ports for the most common Email Clients.<\/p>\n
