I'll answer as best as I know.
Our network runs SBS2003 and Exchange deals with the outgoing mail and
collects it from the hosting company which also hold the website.
SA is configurable from the hosting sites Cpanel (web login) and I'm
assuming that as it 'tags' and 'scores' the mail that Exchange then
downloads, that it is called in after the mail has already been accepted. I
don't really know.
As to control over various settings for SA, the configuration panel is very
basic but I have access to the .configuration file if things need to be
changed in more detail.
As to whether I have access enough to setup grey-listing again, I'm sorry I
don't know.
