i use mail() to send an email but it always sent in spam, how to fix it? and i want to make php script to show something like "warning" in my website when there is any new email, how to do it?please, really need your help!
Spam mails is a complex subject.
First off, are you sending a properly formatted header? The fourth parameter in mail();
Besides that, the rest of the settings are outside of PHP, namely on the mail server.
