SPF email record

Hello Experts,
Our company has recently migrated email servers and we need to verify our SPF records are correct.  Its a simple environment with an exchange box sitting behind a barracuda spam firewall.  Here is what we have: (ive changed the info a bit to protect privacy)

mx record: mx01.somecompany.com
internal exchange server: mx01.eh.local
send connector on exchange: mx01.somecompany.com
receive connector on exchange: mx01.somecompany.com
barracuda spam filter (we run outbound messages through it): ehba-001.somecompany.com

our current spf record:
v=spf1 mx ptr ip4:[] mx:mx01.somecompany.com -all

Here is a bounce back message from a hotmail account:

X-ASG-Debug-ID: 1299333332-03ca88770711720001-lEgx0r
Received: from mx01.somecompany.com (mx01.eh.local []) by
 EHBA-001.somecompany.com with ESMTP id xmFdy9k5s7XQ6JLj for
 <someemailaddr@hotmail.com>; Sat, 05 Mar 2011 07:55:36 -0600 (CST)
X-Barracuda-Envelope-From: sender@somecompany.com
Received: from MX01.eh.local ([fe80::7d84:be4a:4192:9c1]) by
 mx01.eh.local ([fe80::7d84:be4a:4192:9c1%18]) with mapi id
 14.01.0270.001; Sat, 5 Mar 2011 07:53:55 -0600

Do we need to add the barracuda (ehba-001.somecompany.com) to the spf record? Or our internal exchange server (mx01.eh.local)?  

Thanks for your help!!

All that is needed in your SPF record is your sending IP Address.

You can check your SPF record is valid on the following site:


And work out what to put in your SPF record here:

If your current SPF record is:

v=spf1 mx ptr ip4:[] mx:mx01.somecompany.com -all

Then you need to remove the square brackets from around the IP Address so it looks like this:

v=spf1 mx ptr ip4: mx:mx01.somecompany.com -all

In answer to the question, to TEST your SPF record, you have many options:

1) If you have a Linux system, use the command (part of bind/named)
dig txt domain.com
 -- or, if you're using a newer DNS server, try --
dig spf domain.com
In either case, your SPF record will be in the response

2) If you want a web-based test, try here
Good Luck!

Thanks for the suggestions:
I've modified the spf record to read: v=spf1 mx ptr ip4:myaddr -all  and it passes on kitterman.com's website.  However I still receive a 550 sc-002 message from hotmail.

Im concerned by the following header received by hotmail:

Received: from mx01.somecompany.com (mx01.eh.local []) by

Are we sure I do not need to add the ip address of EHBA-001.somecompany.com to the spf record?

Is EHBA-001.somecompany.com the internal FQDN of your Exchange Server?
