I've got a hosting account with MediaTemple and whenever any of my clients, or myself, try to send an email to a hotmail address it just vanishes. I've checked the mail logs with the MediaTemple support team and it is indeed leaving the server.. MediaTemple tell me that Microsoft are very strict on spam etc and may have some form of block.. I've even added SPF records to my domains in an effort to show Microsoft that we're legit, but still, emails are vanishing, no bouncebacks, no junk folder nothing...

Does anyone have any advice for me?

Thanks,

Ben
