Security

Anti-Spam
Multiple testing methods allow administrators to adjust spam prevention techniques and block 99% of incoming spam.

Heuristics and Bayesian engines allow for two different filtering techniques.
DNS and URI Blocklists use numerous third-party servers to determine spam
Greylisting delays inbound mail from unknown senders to discourage spam
Message Certification allows for a third-party to validate a sending server so it is considered friendly
Backscatter Protection prevents receiving irritating bounce messages from messages you did not send
Message Scoring can be customized to fit each domain's needs - each domain can refuse, quarantine or tag messages based on various scores.

Anti-Virus
Flexible configuration to perform automatic updates at regular intervals, ensuring the greatest protection. Messages with viruses may be refused or quarantined for later review on a per-domain basis.

ProtectionPlus for SecurityGateway (Optional)
Extends and compliments the built-in antivirus and antispam features of SecurityGateway, allowing administrators the flexibility to use multiple AV engines in addition to real-time virus and spam patterns analysis.

Kaspersky AV Engine provides best of class antivirus scanning
Outbreak Protection allows SecurityGateway to recognize spam or virus outbreaks almost immediately as they are released over the Internet.

Anti-Spoofing
Multiple techniques are used to verify a sender’s address to prevent spammers from forging the origin of the message.

Reverse Lookups can tag or refuse messages if the sending mail server or email address is forged
Call Back Verify allows SecurityGateway to verify that the sending email address is valid before accepting the message

Email Authentication
Incorporates current authentication techniques used to validate and sign messages to minimize the receipt of possible spam messages.

DomainKeys Identified Mail (DKIM) associates domain names to represent a sender’s identity. Messages are sent with a digital “fingerprint,” which is then validated upon receipt to confirm the signer's identity and to ensure the message was not tampered with during transit over the Internet
Sender Policy Framework (SPF) and Sender ID uses IP-based or path-based methods verify the sender of a message

Anti-Abuse
Multiple techniques to allow legitimate mail in while preventing unauthorized access, all configurable on a per-domain basis.

Relay Control prohibits messages from being accepted or delivered if they are not to or from a SecurityGateway user
SMTP Authentication can force users to authenticate with a username and password when sending mail, if desired
IP Shielding allows SecurityGateway to only accept mail from a domain if it matches a pre-defined domain/IP pair
Dynamic Screening bans senders based on their suspicious activity
Tarpitting deliberately slows sessions when abuse-type activity is detected
Bandwidth Throttling can prevent email services from using all available bandwidth

Filtering
Minimize incoming and outgoing threats by blocking or quarantining messages based on content or types of file attachments

Message content filter allows the administrator to look for content within a message and take action based on the results
Preset file types allows the administrator to tell SecurityGateway to block all attached video files, images, or executable files with one click

Blacklists
Block threats from known email abusers.

Addresses – match addresses by domain or email address
Hosts – match by the host name given during the SMTP session
IP – match by connecting IP address
Blacklist Actions allow the administrator to refuse or quarantine if a blacklist match occurs

Whitelists
Speed up message processing through the identification of friendly senders.

Addresses – exempt email from addresses by domain or email address
Hosts – exempt email by the host name given during the email session
IP – exempt email by connecting IP address

Policy Enforcement
