In this article it is shown that to every non-discrete Hausdorff lineartopology on $\Z$ other metrizable locally quasi-convex group topologies can beassociated which are strictly finer than the linear topology and such that thecharacter groups coincide. Applying this result to the $p$-adic topology on$\Z$, we give a negative answer to the question of Dikranjan, whether thistopology is Mackey.

Linear topologies on $\Z$ are not Mackey topologies
