If you reconnected/restarted MTA and it doesn't work yet, the only solution is to re-install MTA. In addition, concerning the MTA resolution, it'd a hand in this problem.
Guys, anyone found a solution? I tried deleting mta and installed it again and it's still big
If you haven’t, try doing a clean reinstallation - including deletion of all MTA folders to ensure that the settings reset upon fresh install. @ManeXi
