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!
