I thought I'd ask here because dealing with Vodafone support is like pulling teeth and the 24 hour wait between email replies is killer.

We're moving quite a few customers over to GMail who have had a Vodafone email - everything seemed alright for a day or 2, but we've been getting reports that emails from places like Facebook don't come through. We spent a good part of the day on it, and it appears that any email provider that has both DKIM and SPF enabled seems to simply not come through. If we send emails from a domain with no DKIM / SPF records they come through.

Has anyone else run into this issue? Or have we run into an isolated issue? It appears the only time we've seen the issue so far is on @clear.net.nz emails, however just because we haven't had complaints yet doesn't mean the issue doesn't exist on the other domains!

Yes, also a clear.net.nz address.

I have heard of similar issues. Also many posts on Vodafone Community seem to suggest there is something going on too.

Clear/Paradise have always been somewhat separate from the other domains being ex-TCL. clear.net.nz itself was the only domain to have a SPF/DNS record at the beginning of the month but I see that has since been removed. Not sure if related.

CamH:

emails from places like Facebook don't come through.

Best fix is...
Tell them to change all of their email contact details to gmail, ie change Facebook contact email to gmail etc. Yes its a pain .

This isnt going to get better as time goes on, I wouldnt expect voda to keep putting lots of effort into keeping a (almost) dead email system working at 100%

Clear is long long defunct . Be thankfull clear email was kept going for this long & move everything permanently.

Thanks - we absolutely would have done this if we had known it would be an issue, but unfortunately we didn't know until after forwarding that it didn't actually work.

As soon as we can actually regain access to the affected accounts, we'll be sure to change the registered email, but it's very difficult explaining this process to the older generation who are a bit wary of anyone touching their stuff.

The problem you'll be seeing is that Facebook (as an example) have a HardFail set (-all) in their SPF policy, which tells the recipient email server that emails for facebook.com should ONLY come from those defined at _spf.facebook.com (they have a redirect in).

clear.net.nz webmail system is old and I presume does not have the functionality to "remail" instead of forward the emails, which then breaks SPF and is evaluates as a failure at the final email server (Microsoft and co...). (ref)
R-emailing would be the best practice here to avoid these issues.

Normally if a domain is SPF and DKIM complaint, you would only refuse the mail if BOTH mechanisms fail, but allow if neither are setup or only 1 fails - but the problem is not all mail providers function that way, depending on email server compatibility and mail processing policy.

I can confirm my domain which has a strict (-all) policy for SPF and DKIM setup does not get received if I send to my clear.net.nz mail address.

EDIT: it appears that my Office365 account has indeed received my email, but it was mothballed into the junk folder and had a message from Microsoft saying it failed to pass the spoofing protection test.
