php - email from hotmail accounts not received by easyspace mail account

Question

I use the mail() function to email customer completed forms to my easyspace account. However any forms that have a hotmail from email address specified are unreceived. They are not in my spam folder either. If i send an email direct from a hotmail account this doesn't happen. Any ideas why this would be happening?

Answer 1

Never ever use a from address that differs from the domain your site is running on. You can put into reply-to anything you want (including hotmail addresses) but from must contain a legit mail address.
