Can I use my Gmail account to send email from my instance of WatchGuard Dimension?



To send email notifications, your instance of Dimension must have an SMTP server specified in the Email Settings. You can use an SMTP server from inside your network, use a third-party SMTP server, or use your Gmail account. If you use your Gmail account, you can send up to 500 emails per month.

Note: If you select another third-party email provider, make sure that your email provider will allow you to send large amounts of email from an automated application. Make sure to comply with any email-related laws in your nation and region.
