# Why can't I send email messages?

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 are experiencing any issues, please feel free to contact our [24/7 customer support team](/docs/how-do-i-contact-nordlayer-customer-support).
