Aborted pkg install in YaST Mail Server setup, but `zypper ve` doesn't show any problems

I accidentally aborted package installation in YaST Mail Server setup, but zypper verify doesn’t show any problems. Any ideas why? Additionally, consequently, does anyone know how to completely revert the configuration, or redo it from scratch? Performing the process via YaST again doesn’t do anything - it states it can’t start amavis despite amavisd-new being installed.
