This may be because of SPAM list servers, If  your server is do in relaying
for all mails then they will block you mail server ipaddress. go to and give your server ipaddresss for relay test. If it is
blocked then you have to stop relaying in your system

procedure in 5.5

In IMS properties
goto routing tab
in routing restrictions
click two boxes that
1. Host and clients *****
2. Host and clients  with their IPAddresses here you have to give LAN total
network like

after doing this rise a request to relese you IP it may take 18 hours

Good luck

Subject: [exchangelist] Relay problem

Hi everyone.

I have a problem with some Internet freemail accounts.

I have an exchange2000 sp2 setup.

Some of our workers complain that they can't reply to emails that are
sent to their exchange Mailbox.
This problem only occurs when the people use Internet Email, and send
the reply or mail from there.
If they use the OWA or the normal MS exhange Server Email, there is no
problem. It also only happens with some adresses not with all. I haven't
knowingly blocked any Email adresses or providers.

The Error message is (translated from Germann)
"the message could not be sent because the recipient was refused by the
server. Server answer: "550 5.7.1 unable to relay for
reby_g@xxxxxxxxxxx", (account: "domainname", SMTP-Server:
"", error number 0x800ccc79).

Can Anyone help me out on this?

Thanks alot
