We are using MessageLabs for our most of our inward mails. However, we also get mails from other places as well. In order to get rid of spam, we have installed the latest version of spamassassin, which is set to reject any mail at smtp time if the score is over 12. What I find peculiar is some mails from MessageLabs are not scoring as high as the one scored by spamassassin.
Below is the example of the header which has been rejected at SMTP time, 2015-03-12 09:05:51 1YVz3t-0001lJ-6m H=mail6.bemta5.messagelabs.com [195.245.231.135] F=<t...@dodobooking.com> rejected after DATA: This message scored 25.8 spam points.
