Re: hfaxd filling my logs with `-> Got a: 127.0.0.1[13] (how to stop this??)

Looks like one server is capturing "LOG_DEBUG" to system logs, and the
other isn't.  The "Got a: <ip/port>" is a LOG_DEBUG message on in the EPTR
command.  There are a smattering of LOG_DEBUG syslogs in the code, those
could probably be removed.

If you had hfaxd's ServerTracing set to something more chatty (such as
0x33) you would probably see who (network wise) had connected and issued
the EPRT command.
