assistance with helo check error

Hello Everyone,

 

I have a problem which I think the handshaking looks right in respect to the
helo checks, but the receiving postfix server is rejecting messages from a
user.

 

The errormaillog shows:

Oct 18 10:46:14 pluto postfix/smtpd[12109]: connect from
wgfw.serv_mxi.com[112.171.19.161]

Oct 18 10:46:14 pluto postfix/smtpd[12109]: NOQUEUE: reject: RCPT from
wgfw.serv_mxi.com[112.171.19.161]: 554 5.7.1 <clientdomainname.com>: Helo
command rejected: Helo Check; from=<Jackclientdomainname.com>
to=<Jackweb56.net> proto=ESMTP helo=<clientdomainname.com>

Oct 18 10:46:14 pluto postfix/smtpd[12109]: disconnect from
wgfw.serv_mxi.com[112.171.19.161]

 

 

Any ideas what may be happening?

 

Sending server is an exchange 2003..

 

Thanks!
