If you are using an email client such as Microsoft Outlook, Mozilla Thunderbird, or Apple Mail, you may come across an issue where your email messages: - Cannot be sent but can be received - Cannot be received but can be sent - Cannot be sent nor received (There are no issues when you access your email from a web browser.) To solve the problem, try the following: - Change the outgoing and incoming mail ports your email client uses. Our service blocks traffic over the insecure port 25, so use other commonly used e-mail ports such as 587 or 465 - Disable the Web Protection feature in the application settings - Switch to a different NordLayer server. Your email provider may be blocking access to its email services from IP addresses of a known VPN server. Switching to a different NordLayer server may help --- **Note**: In case you have any questions or issues, press '**Chat with support**' at the bottom of the page.
