I'm trying to work out why email I send from one domain I own is rejected by another that I own, and while I think it may be related to how I've setup spf records, I'm not sure what steps I need to take to fix it.

Here's the error message I receive:

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550-Verification failed for <>
550-No Such User Here
550 Sender verify failed (state 14).

Here's the response from

I've registered the spf records for my domain, as advised here

Both domains pass validate according to Kitterman's spf record testing tools, so I'm somewhat confused about this.

I also have the catchall address set up on the domain here, but I don't have one setup for

Instead, we have the following forwarders setup  to  to     to     to

Any ideas how to get this working? I'm not sure what I should be looking for here.

Does it work if you remove SPF?

I've found it to be more trouble than it's worth. It doesn't stop you recieving spam, it only reduces (slightly) the backscatter from people sending spam in your name.

Have you tried turning on the "Catch-all Address" feature in Google apps? If you assign it to a user name you can at least tell if the mail is getting to the Google Apps instance for your domain. Since it seems, from the above error, that Google Apps could not locate the user, perhaps this will help diagnosing the issue.

Are you using the SPF registered server as your outgoing mail server, or some other such as that of your local ISP?

Sorry Devin, I'm not sure I follow you (this is all fairly new to me) Both domains have the following spf record as type TXT: v=spf1 ~all v=spf1 ~all Email is sent using Google's servers in both cases. – Chris Adams Sep 4 '09 at 8:54

The way you have SPF set up (ending in ~all) it is very unlikely that it causes a rejection (especially not the kind you reported). Besides, the port25 check indicates that everything is fine. You can also use to double-check.

As pjc50 suggested, try the mail setup again without SPF records. I guess that SPF records are not an issue here. But we do not have yet enough data for further analysis.

Are you sending all mail through gmail using the "Send Mail as" of the "Accounts and Import" section of GMail? I had this same error when attempting to send email through my gmail account as another of my "Apps for Your Domain" accounts. I had changed the password of my user account and that was why it was rejecting it. It was actually being rejected by GMail and not by the recipient's email server.
