Disrupter OL is a co-process (tech talk: a thread) within Outlook.
This means it waits that Outlook has downloaded the mail and then
starts processing it.
Due to the co-process nature, it does not add any traffic to the
message download like other filter- or pipeline-spam solutions do.
Even the internal speed of Disrupter OL is irrelevant: it can process
messages any time after they have been received. It is possible to
shut down Outlook and restart it next day: Disruptor will process
the remaining messages from last mail exchange! You can continue using
Outlook without even noticing that Disruptor OL does its work.
Remark: due to its co-process nature, Disruptor might need more
or less time to process the messages. Current co-process settings
are designed for optimized foreground reactions of Outlook and other
First daily startup might be slow due the internal housekeeping.
