EmailMode is used to prevent sending emails from @avectra.com email addresses. This can happen if certain system options or templates have these email addresses which can be left over from implementation or testing phases of a project. If any function in netFORUM attempts to send an email from this address, the email will not send and an exception will be logged in the error log.
If you want to disable emails altogether on a test/dev site, then see EnableSendEmail.
EmailMode should be set to Live on a live site. When set to Live, email addresses that contain @avectra as the "from/sender email address" will not be sent. This is designed to avoid confusing members who will not be familiar with Avectra. Clients must ensure that Avectra email addresses are not configured in Live netFORUM sites.
If the value is set to Test, then emails can only be sent to email addresses containing domains specified in the EmailModeTestDomains system option. This option is available as of netFORUM 2012.01.
If the value is set to Avectra, then emails can only be sent to email addresses that contain @avectra.com
