I notice the same thing in my logs, however most but not all is being 
delivered. I tried to telnet with no success. It looks like 64.4.50.179 
is not responding but 64.4.50.239 is working.

 Is anyone having a problem with postfix (Imgate) not delivering
Hotmail and MSN accounts?

it happens from time to time. their MXs get very slow, and postfix 
smtp_*_timeouts  timeout when trying to send

smtp_connect_timeout = 30s
smtp_data_done_timeout = 600s
smtp_data_init_timeout = 120s
smtp_data_xfer_timeout = 180s
smtp_helo_timeout = 300s
smtp_mail_timeout = 300s
smtp_quit_timeout = 300s
smtp_rcpt_timeout = 300s
smtp_rset_timeout = 20s

either you wait for msn/hotmail to clean up their mess, or you increase 
your SMTP timeout JUST to handle the msn/hotmail mess.

The problem is that increasing your timeouts affects all postfix sending to 
all MXs, not just msn/hotmail.  If you look for other smtp.*timeout in your
maillog, you will get some feel for the situation.

with 9000 backed up, you better increase your SMTP timeout dramatically 
just to bet the mail delivered.
