The msg-file section informs the SNFMulti engine about what message file format to expect. This is only useful when scanning message files. When scanning message buffers, the engine always expects to see a complete SMTP message including the local received header.

<msg-file type='rfc822'/>

The type='rfc822' attribute indicates that message files will be in the standard SMTP message format as per rfc822. This is the default since it works for most systems.

At this time, the only other option supported by the SNFMulti engine is type='cgp' which indicates that message files will be in the Communigate Pro format.
