A customer of mine had this exact same problem. He called up hotmail and
apparently it’s a problem on their end when their mail servers get
overloaded.
Yet another reason to not ever get a hotmail account!

We are having the same problem. I h ave been in contact with M$ and here
is what they say:
“Currently MSN Hotmail is experiencing an unusually heavy volume of
incoming mail and this has placed us in the condition of having our
incoming mail servers temporarily saturated with incoming connections. I
would suggest that you make sure that your system is trying to make
connections to more than one IP at a time, that it rotates connections
between different IPs in our MX record, and that you use persistent
connections when you do connect. Many domains will suspect a server of
being a spammer if they stay connected beyond, say, 50 RSET commands,
but our system does not do that. We encourage unlimited RSETs for
efficiency’s sake.”
Oh, goodie. I scanned the listarchive, and my understanding is that
qmail cannot be configured to use persistent connections, i.e. use RSET
to send multiple mail in one connection. Is this correct, or am I
missing something obvious?
