We recently were affected by spam in our office.   Our ISP blacklisted us because of it.  We block the port 25 through out the office.  Only the exchange server can communicate with port 25.  Today I realized that the exchange queue is still loaded with spam messages.   How can that be?  Can spam use someones outlook account to send mail through the exchange?  What can I do to remedy the situation.  How can i find the culprit...
