Re: Hotmail blackholing certain IP ranges ?
- From: Chris Edwards

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.
