@cmb69 there is some inet_addr usage in win32/sendmail.c and win32/inet.c, don't know if worth to be fixed there

From a quick glance, it seems we can drop win32/inet.c/.h altogether, since this has only a fallback definition of inet_aton; or do we need to support it for external extensions?

GetAddr() in win32/sendmail.c should be fixed (it currently doesn't support IPv6). Or maybe drop SMTP support altogether? (It's hard to maintain that Windows specific implementation in the long run.)

@nikic thanks :)
