        Hi,
what is better on local IP (which can be a public IP too), than using
a local host name, which might not be accessible (resolved) from
the outside? Is there related any shame on the chosen computer name?

I can understand the need to "stay anonymous" for spammers or the like,
but regular good citizens might not have a problem with this, maybe?

Looking around, the SMTP transport uses the name only if
g_resolver_lookup_by_address() returns anything for the address
returned by g_socket_connection_get_local_address(). There is no option
to skip this lookup.
        Bye,
        Milan

P.S.: for some reason, your reply to Patrick doesn't contain headers
for proper threading. Maybe your mail client needs a fix to include
In-Reply-To and References headers in replies. Just saying, no offense
meant.
