Re: [INTERNALS-WIN] mail() sending local hostname instead of fully-qualified hostname as HELO

Hi Kalle,

I've created a new patch which makes the following changes:

* Fixes a small bug in your last patch which would inadvertently set the 
host name to "]".
* Performs some overflow checks.
* It turns out that host names are technically allowed to start with (or 
even be entirely composed of) numbers, so I've taken your suggestion and 
used inet_pton for better IP detection.

Here's the patch:

I've tested it by forcing ent->h_name to an IPv4 or IPv6 number, and all 
three scenarios (including not forcing it) seem to provide valid data.

Cheers,
