Re: Hotmail blackholing certain IP ranges ?
Some sites have recently reported problems mailing hotmail due to inability to resolve the hotmail MX records. This appears to be due to the hotmail DNS servers now blackholing DNS queries where the UDP source port was < 1024. I can reproduce this here and now, but don't know if it's new.
