SPF Sending email 127.0.0.1

[iceruam]

I am receiving errors sending email, I have been using zimbra for 6 years now, that state:
451 spf lookup failure (#4.3.0) I am not sure, but I be because my email is being stated as sent by 127.0.0.1.
How would I put another ip address in there?
Could this be the issue, I have not had issues until today and have sent to this client numerous times.

Thanks

No, that's not the issue it's a DNS problem: +"451 spf lookup failure (#4.3.0)" - Yahoo! Search Results

OK, wow hate re-reading my posts sometimes ' but it may be because' is what I meant....
anyhow
DNS, and how do I fix it, is it my issue or who's problem is it? The stuff I read on the internet is very vague on what the error is, lots of questions and some replies that are not very easy to comprehend.

I still have 10 email's setting in Queue with this error I am not sure how to resolve this, does anyone know where I can look to resolve it, is it my end or theirs?

Why don't you check your DNS SPF records? Did you read any of the links I gave you? I'll also remove your duplicate post.

Resolved, I had to create a TXT record on the domain host. yeah I read through the links...did not find them useful the last post you posted pointed me in the right direction. Thanks

is this a security concern...this is what I put in my TXT record(with the quotes and my domain): "v=spf1 a:domain.com -all"
