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.

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?

 

Todd

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 
space or a dash, then the host name). If your mailserver sends out E-mail using 
this domain in its EHLO or HELO, your E-mail might get blocked by anti-spam 
software. This is also a technical violation of RFC821

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.
