Usage Guidelines

By default, the system scans viruses on files both uploaded and downloaded using IMAP.

If no response action is configured, the default action alert takes effect.

The client/server type of protocols supported by the AV function also applies to the direction.

Upload: The file is sent from a client to a server.
Download: The file is sent from a server to a client.

Connections are generally initiated by a client. To ensure that connections can be established and the AV process can be implemented successfully, configure the zone of the client as the source and that of the server as the destination when you configure the security policy.

Example

# Create profile av_imap, configure AV scanning on files both uploaded and downloaded using IMAP, and set the response action to declare.

[sysname] profile type av name av_imap
