We recently getting e-mail bounce back when e-mailing certain people. It's always been fine but it started happening about 2 weeks ago.

An example of the bounce back message is:

This is the mail system at host abc.abc.abc.net.

I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can delete your own text from the attached returned message.

                   The mail system

<abc@abc.com>: host cluster.abc.abc.com[xxx.xxx.xxx.xxx]
    said: 553 Sender Policy Framework (SPF) fail (in reply to RCPT TO command)

Any advice on how I can get this resolved?

you need to have an SPF record in your public DNS that specifies the public IP address of your server to show it's allowed to send for your domain (not all receiving mail systems do SPF check)

for example, your SPF value (as a DNS TXT record with name of @ and TTL value 1 hour is sufficient) would look like this:

v=spf1 mx -all

this assumes your receiving server that's in your mx record is the same as what it goes out as; if it's different then you will need to replace 'mx' above with it's address in the format of ip4:<address>

once that change is made, it will take a little time to propagate
you can verify with nslookup with a google public dns server

nslookup - 8.8.8.8
>set type=txt
>abc.com


and should show the spf record you just added

here is a more detailed explanation of SPF records
