I'm not familiar with POP3Client but skipped tests are not normally something to worry about.

It's normal for some modules/tools to skip certain tests that are platform specific or that require optional modules that aren't installed. You shouldn't be too worried unless tests are reporting failures.

It's also possible that the author didn't write a test script but the installer requires one. In this cause, the author could have written a test with one step that gets skipped just to satisfy the installer.
