If you can’t send emails while connected to the VPN, it could be because your email client application is using TCP port 25, which is blocked on the ExpressVPN network to prevent spam. This can happen especially with old email applications. To resolve the issue:
- Allow access to local network. This can be done on your ExpressVPN app as follows:
- Windows: Go to ≡ > Options > General then checking the box for “Allow access to local network devices such as network shares or printers.”
- Mac: Go to ≡ > Preferences > General then checking the box for “Allow access to local network devices such as network shares or printers.”
- In the ExpressVPN app, go to Settings (Windows) or Preferences (Mac) > General > Connection Per App. Click on Settings and set the email client you are using to NOT use VPN.
If above steps do not work, you may need to:
- Switch to a newer email client such as Outlook or Thunderbird, or manually configure your email client to use port 587 instead of port 25. Outlook users will need to select the type of encrypted connection for the outgoing server before entering 587 for the Outgoing server (SMTP) port number. See details here.
- Disconnect from ExpressVPN to access your email. This may be necessary if you are using your ISP’s email server and it blocks email traffic coming from outside of its own network.
