We have an issue where Email is being tagged with [SPAM] within the same domain, for example: user1@domain.com to user2@domain.com. It is not using ****SPAM**** like SpamAssassian should be using so I am at a loss as to where this could be coming from. The customer is saying they are both using Outlook which I don't think tags, only puts into the junk mail folder. Does anyone know where I might look and change this?
