MX Guarddog is a cloud email gateway for standard SMTP servers used with owned domains. It scans incoming mail for spam, phishing, malware and viruses, quarantines offending messages, and forwards clean mail to the customer’s server. It does not support consumer Gmail or Hotmail accounts. The hosted service needs no hardware or software installation and no changes to email clients or the server. Users receive quarantine reports and can adjust report preferences; quarantine retention is seven days. If a customer’s server is unavailable, MX Guarddog says it can hold mail for up to 168 hours and deliver it once the server is back online. It can sync active email addresses from Windows AD, LDAP or cPanel. Pricing is 0.25 USD per email address per month, with no charge for user or domain aliases. A free service option is available by earning tokens through visible MX Guarddog text links on a website. The SLA commits to commercially reasonable efforts to maintain at least 99.95% uptime over a trailing 30-day period, with a service credit if missed.
Who it is for
MX Guarddog suits organizations, schools, churches, government offices and personal domain owners using standard SMTP servers for owned domains. It is not for consumer Gmail or Hotmail accounts.
