MX Guarddog vs Vircom modusCloud

MX Guarddog is a hosted email gateway for standard SMTP servers serving owned domains. It scans incoming messages for spam, phishing, malware and viruses, quarantines offending mail, and forwards clean messages to the customer’s server. The service runs in the cloud, so it requires no hardware or software installation and no configuration changes to email clients or the server. Quarantine reports summarize stopped spam, and users can adjust report preferences; quarantine retention is seven days. If a customer’s server is unavailable, MX Guarddog says it holds mail for up to 168 hours and delivers it when the server returns. It can sync active addresses from Windows AD, LDAP or cPanel, and says it uses Transport Layer Security, including Perfect Forward Security, for email in transit. The listed per-address price is $0.25 per month; aliases are not charged. A free plan and 30-day trial are listed. The service is for web use and does not support consumer Gmail or Hotmail accounts.
