1) Blocking SMTP by VPN:

– SMTP: The Simple Mail Transfer Protocol (SMTP) is responsible for sending emails over the Internet.

However, certain VPNs may unintentionally block SMTP traffic, hindering your ability to send emails. – Reasons for SMTP Blockage on VPN:

– As VPNs prioritize user privacy, they often block SMTP to prevent spammers from exploiting their services.

– The high volume of outbound SMTP traffic can trigger suspicion in VPN servers, leading to blockage to preserve server resources. 2) Solutions for SMTP Blockage on VPN:

– Using a Webmail Provider:

– Many webmail providers like Gmail, Outlook, and Yahoo offer web-based email clients that circumvent SMTP blockage.

– By accessing your email through their webmail interface, you can bypass VPN-related SMTP restrictions. – Ensure that you connect to these services using the SSL port TCP 465 for secure transmission.

– Changing VPN Service or Whitelisting Email Server:

– Consider switching to a VPN service that doesn’t block SMTP traffic, such as ExpressVPN which offers unobstructed email communications. – Alternatively, contact your VPN provider and request them to whitelist your email server’s IP address, granting it exception from their SMTP blockage measures.

– Switching to a Newer Email Client:

– Some email clients, especially older versions, may utilize TCP port 25 for SMTP communication which is often blocked by VPNs.

– Upgrade to newer email clients that support alternative ports like TCP port 587 or 465, allowing uninterrupted SMTP transmission. – Temporarily Disabling VPN:

– If all else fails, you can temporarily disable your VPN while using your email client to send emails.

– This allows you to utilize your regular internet connection for SMTP communication, ensuring uninterrupted email delivery. – However, exercise caution when disabling your VPN, especially if transmitting sensitive data, to maintain your online security.
