5 things to do when SMTP is blocked by VPN
Is SMTP blocked by VPN on your Windows PC? Are you having issues sending or receiving emails in your custom webmail while on VPN? Do not panic! Windows Report will show you how to bypass this problem.
SMTP (Send Mail Transfer Protocol) is the protocol used by an outgoing mail from a PC. This protocol is generally used during Mail exchange. SMTP is provided by ISP and has a particular address through which these mail exchanges are sent from such as TCP 25 used by many older email client programs.
Reasons why your VPN blocks SMTP
SMTP can be blocked by different reasons apart from your VPN. This particular problem can especially be felt when you travel outside your ISP coverage area. You may have difficulties sending mails from email clients such as Microsoft Outlook, Mozilla Thunderbird, and other email clients. This is usually caused due to differences with the ISP on your device. For instance, some hotels have checks that search if your ISP is from that region; however, if it’s not, your SMTP may be blocked.
Another reason why SMTP is blocked while you are on VPN is because of “spam”. Many reputable VPN providers do not keep logs which mean they must block spam messages. One way they reduce spam messages is by blocking SMTP traffic. Most VPN block outgoing SMTP on port 25; this is because this port is unsecured. However, MS Outlook and several email client programs use this port as the major port for SMTP mails.
Meanwhile, Windows Report team has come up with applicable solutions that can help you workaround “vpn smtp blocked” problem. These solutions are based on practical experience and can resolve the problem of your VPN blocking SMTP.
How to fix SMTP blocked by VPN
Solution 1: Use a webmail provider
Most of the complaints about VPN SMTP blocked issue emanated from custom webmail users. An example of a custom webmail is firstname.lastname@example.org. However, using a standard webmail is an excellent solution since most webmail provides SMTP server on an SSL port TCP 465. Moreover, many VPN do not block this port because it is secure.
This is because these webmail providers are not blocked by several VPN service providers. They also have a huge user base and provide excellent anti-spamming and security features for users. Also, they are free to use and easy to access unlike email clients.
In addition, many webmail providers provide anti-spamming features for users which reduce the number of spam messages entering your inbox. You can pick from many available webmail clients online. However, we recommend the use of Gmail, Yahoo Mail and Hotmail.
Solution 2: Contact your VPN provider to whitelist email server
Many VPN providers provide options for users to contact technical support to whitelist their email servers. You can easily check from your VPN customer service if such option is available. Many VPN would require the following information before your email client can be whitelisted.
- The email address blocked
- The Port number that serves as protocol connecting to the mail server
- Email SSL setting
- The SMTP email server name
Alternatively, you can also bypass this blocks by simply changing the SMTP server settings on your email client to the TCP port.
Note: in order to get rid of this type of issues, you can switch to the best VPN on the market, CyberGhost 7 for Windows. This tool has a wide range of features and setup possibilities plus a great compatibility with Windows 10 PCs. We strongly recommend you to try it and secure your connection.
Solution 3: Temporarily disable VPN
A quick fix method which bypassed the SMTP blocked on VPN issue is to temporarily disable your VPN, send the email with your email client, and then enable your VPN afterwards. This would effectively work; however, there are many dangers involved.
You could be exposed to hacks and attacks from trackers. Also, if you’re sending a sensitive email it can be intercepted by your ISP or government agency. This can be dangerous if you’re in a region with strict government censorship on the Internet.
Solution 4: Switch to a newer email client
Many new email clients do not use TCP port 25 for their SMTP serves. If your VPN still blocks your SMTP, you would have to upgrade to a newer version. Alternatively, you can replace your email client with the latest email clients that use much more secured TCP ports.
Some of the latest email clients we recommend include Mailbird (our Nr. 1 choice). This is a great tool which has a free version and includes multiple email accounts. It also allows you to classify and organize your emails thus making your email work easier.
