SPF Records for Blackberry Users


If you use a Blackberry and are considering implementing SPF (good) then you will need to add the following parts to your SPF record. This is to allow the Blackberry smtp servers to send mail on your behalf when you send mail from your handheld device.

ip4:206.51.26.0/24 ip4:193.109.81.0/24 ip4:216.9.240.0/20 ip4:204.187.87.0/24

So, a sample SPF record would be:

mydomain.com IN TXT v=spf1 a mx ip4:206.51.26.0/24 ip4:193.109.81.0/24 ip4:216.9.240.0/20 ip4:204.187.87.0/24 ~all

    Is it really necessary to add so many IPs to SPF just for RIM SMTP? There isn’t a shorter list of IPs that can be added?

  2. Increase Search Engine Ranking Says:

    Yes, because in order to provide the service, they have to have redundant servers. Ideally, it would be nice if they used a Radware type device though, or a cluster that was behind a public IP.

    Just my nickle

    I’ve only really started really digging in to SPF the past day or two but from various things I’ve read, it seems like it would be better to add:
    include include:srs.bis.eu.blackberry.com
    and/or include include:srs.bis.eu.blackberry.com
    so that you would have to be less concerned about the ip addresses of the Blackberry service’s mail servers. The na (North America) one includes the ip addresses in our post. I didn’t check the eu (Europe) one.

    I’ve seen multiple posts in various places listing all of the IP addresses with ip4: directives as you mentioned, but I only found the include idea in a comment on another blog, which no one even responded to. Am I missing something bad about using the include?

    I know it’s a long time ago but I thought I’d comment anyway.

    I’m “into” SPF and as you say the “include:some.record.tld” is good as it makes your own TXT record shorter and in my opinion it also kind of implies that you’re including someone elses pre-prepared record which I think makes sense way more than a list of random IP4:s whose ownership and origin are unknown.
