In 2020 the TRE regex library will be removed completely and all posix spamfilters will cease functioning. This will also mean that if you mix 3.2.x and 4.x networks at that time, then the 3.2.x spamfilters will no longer work on 4.x servers. This should not be a problem as all support for 3.2.x has been dropped on Januari 1, 2017.
