Over the past years, research has highlighted the importance of enhancing the performance of e-mail spam filters to eliminate the risk of false negative e-mails. On the other hand, the problem of false positive e-mails got less attention despite the fact that it is critical and may cause a failure in the delivery of important e-mails. The aim of this research is to provide a solution to reduce the rate of false positive e-mails. It addresses the problem by exploring the behavior of the existing e-mail spam filters and highlighting the different reasons behind the failure of e-mail delivery. Based on this investigation, we developed an algorithm that helps e-mail users in ensuring the deliverability of their emails. The proposed algorithm is based on reversing the mechanism of spam filters on the client-side.
