    If you have installed a VPN and are experiencing issues sending email messages while still receiving them, it may be related to the VPN settings or the way it interacts with your email client. Here are some steps you can take to resolve this issue:

    1. Check VPN Settings: Ensure that your VPN is configured to allow email traffic. Some VPNs may block certain ports used for sending emails (like SMTP).
    2. Change VPN Protocol: If your VPN allows it, try switching to a different protocol (like OpenVPN, IKEv2, etc.) to see if that resolves the issue.
    3. Disable VPN Temporarily: As a troubleshooting step, temporarily disable the VPN and try sending an email to see if it works without the VPN.
    4. Firewall Settings: Check if your firewall settings are blocking the email client while connected to the VPN. Adjust the settings to allow your email application to send messages.
    5. Update Email Settings: Ensure that your email client settings are correct, especially the SMTP server settings. Sometimes, VPNs can change network configurations that affect these settings.
    6. Contact VPN Support: If the issue persists, consider reaching out to your VPN provider's support for assistance, as they may have specific configurations or solutions for email issues.

    Following these steps should help you troubleshoot and potentially resolve the issue with sending emails while using a VPN.

    Hi Mark,

    Who is the Email service provider? Many email providers block VPN-associated IP addresses from SMTP access because these IPs are frequently abused for spam and are used to obscure the sender’s true identity.

    Try turning off antispam / email scanning features in your VPN program and see if it resolves the issue.

    I’m eager to hear back and work together to find a solution.
