This issue is not about getting test_logging to work in a particular way; test_logging is exercising SMTPHandler and (AFAIK) tidying up after itself, with no sockets left open.

When working on the test, I just noticed that smtpd forces use of the global socket map, which is not ideal ("The fact that asyncore uses a global socket map is surely unfortunate" - Giampaolo). Given that asyncore's design allows for a socket map to be passed in (at least in part - RDM's comment), ISTM that it should support this consistently, and also that smtpd should support this mode of use.
