Butchered logs make it difficult to help you, the "xx" and "w.x.y.z"
need to be shown unaltered, so that they can be compared with the

"xx" equal to "mta.one"?

Well, the default connection count limit is 50 not 10, so your
configuration settings are not as reported, perhaps you have master.cf
overrides, or additional settings lower in main.cf.
