I've been told this is quite hard...but please hear me out before you start running. I am hosted on a sub-domain and I want to be able to use the mail() function to send my users emails (obviously with their permission). However the emails are sent to their Junk Mail Box...and not everyone reads the notices and is smart enough to check in there and then complain about not receiving the email. I have searched and searched and searched all day and finally came up with the conclusion that I need to add an SPF record in my DNS zone file. The only problem is I don't know what the DNS zone is and how to configure/make/edit it...I do however understand what the SPF record is and how it affects the emails... Can anyone shed some light on my problem, Muchas Gracias, Jordan
