When connected to Avast SecureLine VPN, you may experience problems while trying to send emails from email client, such as Microsoft Outlook, Mozilla Thunderbird or Apple Mail (Mac).
Configuring outgoing SMTP server settings in your email client to use the port 465 or 587 and SSL/TLS encryption usually solves the issue.
If you are using Gmail or Windows Live we recommend to configure your email client to use a specific IP address of the SMTP server instead of its hostname (smtp.gmail.com or smtp.live.com), as these email service providers are known to use multiple SMTP servers.
Since we have no control over these servers, we don't know the full list of IP addresses.
