553-Message filtered - HELO Name issue?
- by g18c
I am having major issues sending from my SBS2011 machine to Message labs server-13.tower-134.messagelabs.com #553-Message filtered. Refer to the Troubleshooting page at 553-http://www.symanteccloud.com/troubleshooting for more 553 information. (#5.7.1) ##
I have changed the IP and hostnames from the below.
I am not on any IP or domain blacklists.
I have setup SPF (which includes mailchimp servers): v=spf1 mx a ip4:95.74.157.22/32 a:remote.mydomain.com include:servers.mcsv.net ~all
I am sure i have setup my HELO names correctly under the Exchange Management console, sending a test email from the SBS server and looking at the header shows the following:
X-Orig-To: [email protected]
X-Originating-Ip: [95.74.157.22]
Received: from [95.74.157.22] ([95.74.157.22:52194] helo=remote.mydomain.com) by
smtp50.gate.ord1a.rsapps.net (envelope-from <[email protected]>) (ecelerity
2.2.3.49 r(42060/42061)) with ESMTP id 11/90-10010-E529C835; Mon, 02 Jun 2014

Received: from MYSBSSVR.mydomain.local ([fe80::3159:95a6:23f:1bef]) by
MYSBSSVR.mydomain.local ([fe80::3159:95a6:23f:1bef%10]) with mapi id
14.01.0438.000; Mon, 2 Jun 2014 19:03:56 +0400
Is is the main helo name there OK and do i need to worry about the second Received block where the MYSBSVR.mydomain.local is mentioned?
I have asked the ISP to set the reverse DNS for my IP to remote.mydomain.com but they have instead put remote.MYDOMAIN.com - would this case cause HELO lookups to classify this as not matching?
Anything else I can do to find out why i am being filtered?
