Setting up SPF records

Dear Experts

Please can someone assist me.

I need help setting SPF records in my environment.

I run a hybrid exchange 2010 / 365 with Cisco IronPort C370 as my MTA.

Appreciate any advice.

If you have already setup your IronPort for SPF(http://www.cisco.com/c/en/us/support/docs/security/email-security-appliance/117973-faq-esa-00.html).  
The only other thing to do is to create the SPF record on your DNS Server.  You can use the below to generate the DNS record for SPF.

Hi Anthony

Apologies for the delay. This might seems like a stupid question but do I have to setup SPF records on my Ironport?

I thought that I only need to add the SPF entries to my DNS records?

:)  There are no stupid questions.  Stupid questions are the ones you don't ask.

Yes, you need to configure IronPort to use SPF.  The SPF DNS records are for the IronPort to reference to.  

Which option to choose, well that depends on your requirement.  See the below.
