Prerequisites

When Email Gateway Security is deployed in the scalable mode, then the minimum hardware requirements apply to each of the primary instance and all secondary instances.

For details about the shared database see Scalable deployment, Scalable deployment related registry configuration and Scalable deployment operation.

Please note that this hard disk space is only enough for installing MetaDefender Email Gateway Security and for very limited operation.

Quarantine and permanently failing emails (especially with large attachments) may consume huge disk volumes.

For performance reasons it is not recommended to use HDD instead of SSD.

When Email Gateway Security is deployed in the scalable mode, then the shared database port must be available inbound on the primary instance, and outbound on all the secondary instances.

For details about the shared database see Scalable deployment, Scalable deployment related registry configuration and Scalable deployment operation.

The anti-spam and anti-phishing filters use a cloud based service to look up patterns. To set up proxy for the anti-spam and anti-phishing cloud service use the antispam_proxy_ip and antispam_proxy_port Registry tunables. For details see Registry configuration.

To implement the exception rule, the OPSWAT installation folder (C:\Program Files\OPSWAT by default) must be excluded from the relevant anti-malware product’s real-time protection.
