Message filter syntax question (header-dictionary-match)

[Vinay babu]

I would like to know does the below message filter looks for Display email address or Envelope email address ? 

I have added few email addresses in the Whitelist dictionary.

Whitelist: if (header-dictionary-match("Whitelist","From", 1))
{
skip-bulkcheck();
}

That is the display name header.

The from indicates the friendly “From” or outlook client from value.

Whitelist: if (header-dictionary-match("Whitelist","From", 1))

The envelope sender|responsible sender|mail-from, as determined within the message tracking would look like this: (mail-from-dictionary-match("skipmacro", 1))

Thank you,
