smtp service in IIS 6

Hello,
After last critical updates my smtp-server return this message:
"Message delivery to the host 'xxx.xxx.xxx.xxx' failed while
delivering to the remote domain 'domain.domain' for the following
reason: The remote server did not respond to a connection attempt."
for every email.
Maybe this update change iis settings? I don't know.
but i can't send i receive email.
Please help me with setup.
thank you.

This is a problem that is becoming more and more common and may not be
specific to your update.

Unfortunately, Microsoft does NOT currently put the remote server's true
reply in the event log message. Micrsoft, pleeeasse do that! To find out
why the remote domain won't accept you, get onto that machine and manually
open a TCP connection on port 25 trying to send mail to the address (a test
message). In the course of doing that, you might see one of many different
things -- like perhaps they're blocking your IP address for spam protection.
Search google for TCP and sending mail manually with the HELO command and
you'll see how to do it.
