You're not giving us much information to go with, but I think the answer lies in the log you gave...."Message 5CC135E6875.B0DB4 from client ip (info@mnlogistics.com) to example.net is spam"....Probably intercepted by Spamassassin, who's name also appears in the log.

You need to be more specific and give more details if we are to help you
