yes, do not use exists in your SPF record if you want SPF to work with hotmail (and may be others).

Medium/large receivers are likely ignore exists: specifications because they don't query SPF at SMTP time, they use a pre-crawled copy of the relevant DNS records. Note that the only problem that exists: uniquely solved (being able to find out who is sending email claiming to be from your domain) is now part of what DMARC does anyway. - Roland On 19/12/2012 22:18, Tim Draegen wrote: Henrik, I may be misremembering this, but there may be issues with the exists mechanism and hotmail. If you can, you might try to remove your exists: check for a few days to see if your data changes. =- Tim On Dec 19, 2012, at 5:16 AM, Henrik Schack <[email protected]<mailto:[email protected]>> wrote: No, it seems to be mostly email send directly to Hotmail.
