Most likely, their outgoing email is NOT going through Postini, most do not.
Postini is mainly used for incoming.

Add their IPs to your global accept list; message delivery; properties;
conection filtering accept. This will exempt all processing. 

 

I"m thinking it's failing because they are going through postini so postinit
says to you helo I"m postini and then sending as their customer's domain.

I do not know, as I did not get to see the header info.

First, what is their HELO as your server saw it?

 

BTW, that answer from them unfortunately is the attitude many take, "It is
your problem, not ours."

Thanks John. Yes their servers are not sending, using, Sender ID. according
to their Exchange Admin, who called me. To say that I should white list them
as he is not changing their servers.

Now my problem is how do I white list them for Sender ID. I do not see a
place to do this in Message Delivery Properties. Any suggestions?

You are rejecting their email based upon your configuration, in this case
because the HELO of the sending server does not meet the requirements of
your implementation. The DNS report you listed means nothing in this case,
since they are sending out through a different server from what they are
receiving on.

 

What you need to do is review the log or if the postmaster message includes
the sending (email) server HELO. This is what is wrong.

Email going out of your server or to your server?

One of our customers e-mails was returned to them with the above error
message. I e-mailed them a DNSstuff report with this error

WARNING: One or more of your mailservers is claiming to be a host other than
what it really is (the SMTP greeting should be a 3-digit code, followed by a

anti-spam software. This is also a technical violation of RFC821

in the SMTP greeting should have an A record pointing back to the same
server. Note that this one test may use a cached DNS record.

They called me back to say that they do not use sender ID and that my
Exchange server is configured wrong. I am running Exchange 2003 SP2, IMF,
RBL and anti-spam software on the Exchange and ISA2006 servers.

Do I have something wrong in my configuration that caused the 550 5.7.1
error.
