Can't send or receive email from hotmail but I'm not banned

[Skin]

Hello,
I've a new VPS which have some mail problems:
I can't send or receive e-mails from hotmail, but hotmail staff assure me that my ip is not in their blacklist:

Hello,

My name is Rupa and I work with the Hotmail Sender Support Team.

I do not see anything offhand with the IP xxx.xxx.xxx.xxx that would be
preventing your mail from reaching our customers. As per our research, the IP
is not on any active block list.

If I send an email to any hotmail account It returns back:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

The part that seems strange to me is:

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

[email protected]
retry time not reached for any host after a long failure period

May be exim is blocking all e-mails directed to hotmail?
Or may be exim databases are corupted?
May be it is an issue with my VPS network or routing and it has nothing to do with exim?

Thanks for any suggestions.

Take a look at a full smtp transaction for a sample mail - i.e is your VPS able to resolve the hotmail mail exchanger (mx) servers and communicate with them on a basic level

What can happen is that your ability to resolve a given service such as hotmail may be temporarily interrupted for a variety of reasons, exim then caches this result - the root failure is generally in the ability to resolve the mail exchanger.

it seems that there are no mail routing errors:

Looks like exim will not re-attempt to send messages at hotmail.

may be I can clear the retry database.....

I found this thread: http://forums.cpanel.net/f43/t-remote_smtp-defer-53-retry-time-not-reached-any-host-72383.html

It is still a valid solution?

/usr/sbin/exim_tidydb -t 1d /var/spool/exim retry > /dev/null
/usr/sbin/exim_tidydb -t 1d /var/spool/exim reject > /dev/null
/usr/sbin/exim_tidydb -t 1d /var/spool/exim wait-remote_smtp > /dev/null

P.S. ThinIce thanks for your hints

Hello

Try connecting to one of Hotmail's mail servers over port 25 from your server with a command such as:

# telnet mx4.hotmail.com 25

You should receive an output like this:

[~]# telnet mx4.hotmail.com 25
Trying 65.55.92.184...
Connected to mx4.hotmail.com.
Escape character is '^]'.
220 SNT0-MC4-F9.Snt0.hotmail.com Sending unsolicited commercial or bulk e-mail to Microsoft's computer network is prohibited. Other restrictions are found at http://privacy.microsoft.com/en-us/anti-spam.mspx. Mon, 10 Jun 2013 06:31:44 -0700

If you do not get a similar result, then traffic may be filtered. Do you have a third-party firewall installed on the cPanel server, or custom IPTables rules in place? If so, you should check to make sure there are no restrictions on email in place. Or, you may need to consult with your data center or hosting provider to see if they are blocking traffic to Hotmail.

Thank you.
