IMSVA 9.0 allows you to manage your SMTP and HTTPS certificates and trusted CA certificates.

IMSVA 99.0 enables you to define rules to submit email messages with specified attachment types to the Virtual Analyzer for analysis.

Social Engineering Attack Protection detects suspicious behavior related to social engineering attacks in email messages. When Social Engineering Attack Protection is enabled, the Trend Micro Antispam Engine scans for suspicious behavior in several parts of each email transmission, including the email header, subject line, body, attachments, and the SMTP protocol information. If the Antispam Engine detects behavior associated with social engineering attacks, the Antispam Engine returns details about the message to IMSVA for further action, policy enforcement, or reporting.

Known hosts include trusted mail transfer agents (MTAs) and the Cloud Pre-Filter that are deployed before IMSVA on your network. IMSVA 9.0 enables you to specify known hosts to exempt them from IP filtering and graymail scanning.

IMSVA 9.0 allows you to group multiple downstream message transfer agents for better load balance and failover capabilities.

IMSVA 9.0 supports both predefined and customized DLP compliance templates based on various data identifiers.

Graymail refers to solicited bulk email messages that are not spam. IMSVA manages graymail separately from common spam to allow end users to receive wanted graymail messages. IP addresses specified in the graymail exception list bypass scanning.

IMSVA 9.0 supports DKIM signing for outgoing email messages.
