For whatever it is worth:
I started having the same problem with hotmail on Friday (could have
started before then, but I know it was happening Friday), I am running the
latest qmail-ldap (which has the dns patch). I have sent email to hotmail
from the same box in the past. I sent some email from the server at work
(exact some setup) and they went through fine. I am not sure why this
problem just came up out of no where, the only thing I could figure would be
that I only have 32MB of RAM and I have had a few minor problems with
qmail-ldap dealing with the low amount of RAM in the past (although my swap
is hardly ever used).
In any event I had been planning on installing dnscache on the machine
anyways, so I did and the problem went away after that.
I doubt that the above information will be of much use, but I thought I
would just throw it out since we had near to the same problem with the same
domain.
