It was a wild guess based on some weird behavior I saw with a SMTP client
a few years back.

Unable

The difference between having a hostname or an empty string in the message
is a result of where in the code this exception gets thrown. During
connecting and some areas where the hostname is 'known', it will include
the hostname in the exception (error code isc_network_error), in other
areas it throws the exception without including the hostname (because that
isn't known in that part of the code or one of us forgot to include it in
the exception), this results in an empty string in the error message. In a
future version I will probably change this to use a different Firebird
error code that doesn't expect the hostname (or maybe do something Jaybird
specific).
