GFI MailEssentials
Stops spam, phishing and malware at the mail server before it reaches users.
GFI MailEssentials — spam, phishing and malware filtering for mail servers
Rising volumes of spam, phishing and malicious attachments create noise and risk for on‑premises mail estates. Small IT teams and resellers often need a filter they can run at the server or gateway without a large operations overhead.
GFI MailEssentials applies signature, heuristic and reputation checks alongside content and attachment rules to quarantine, tag or delete messages. It gives control teams a way to reduce user exposure to unwanted and malicious mail while tuning detection to local needs.
How organisations typically use GFI MailEssentials
Run as an on‑premises filter on Microsoft Exchange or any SMTP server to stop spam and malware before delivery. Typical work focuses on tuning thresholds, safe lists and attachment policies to fit local mailflows.
Used by managed service providers and resellers as a per‑tenant filter or gateway layer where customers prefer on‑site control or have limited cloud options.
Where this product best fits
Fits small and medium organisations or MSP customers running on‑premises Exchange or SMTP servers, and where budgets or policies favour local filtering. It suits teams with limited in‑house email security expertise that need a configurable server‑side control.
Features
Upto 3 Anti-Virus Engines
GFI MailEssentials includes Avira and BitDefender antivirus engines for robust email protection with minimal system impact. For ultimate security, add Sophos. Multiple engines ensure rapid detection of new threats.
Advanced Anti-Malware
GFI MailEssentials offers advanced malware protection by scanning unknown executable attachments via a cloud service. The intelligent Kaspersky cloud engine thoroughly checks these attachments for malicious content.
Multiple Anti-Spam Filters
GFI MailEssentials offers robust anti-spam features, including SPF authentication, greylisting, directory harvest protection, DNS blocklists, Bayesian filtering, and a language detection plug-in. Together, these technologies deliver a spam detection rate exceeding 99%.
Email Safety and Productivity
GFI MailEssentials integrates with any email server, on-premises, virtual, or cloud-based. IT admins manage security, while users can access quarantined emails, release messages, and customise their own block and allowlists.
Visibility and Reporting
GFI MailEssentials allows you to manage email security, including reporting and quarantining, from a single web-based console. Customise reports easily, and view real-time status and email flow via the dashboard.
Quarantine Management
GFI MailEssentials lets you control spam and malware handling. Quarantine emails, notify users, or send regular digests. Users can release quarantined emails, and automatic allowlists reduce false positives for outgoing recipients.
Content Enforcement
GFI MailEssentials scans emails for keywords and attachments. Block specific file types or potentially malicious attachments. Advanced filtering rules let you block emails based on custom patterns, like regular expressions.
Stop Exploits and Trojans
The GFI MailEssentials Trojan and executable scanner detects unknown, potentially malicious executables. It disassembles them, assesses risk, and compares actions to a database of threats, quarantining any with suspicious behaviour like network connections or address book access.
Phishing and Spyware Protection
GFI MailEssentials blocks phishing emails by comparing content and URLs against an updated database and checking for phishing keywords. It also detects spyware using its antivirus engine and extensive spyware database.
