使用php发送自动电子邮件时出现SPF问题

Question

I am having a SPF issue sending automatic email to users that register to my website.

When looking at the "original" email in gmail I got the following message with my Cpanel and hostname details instead of the email I sent the email from and my website name. When sending manual emails using webmail it is working just fine.

Here is what I get from Gmail

To send the email I am using the php mail function

mail($useremail, $subject, $emailBody, $headers);

Any idea about what am I missing? Cheers

Answer 1

Try to use 5th argument of mail function

mail(to, subject, message, headers, "-fyour@email.com");  

otherwise sendmail uses account information in return-path field.

Answer 2

If you send email this way the host server will use the default address for your account as a return path. You can try adding a fifth parameter to mail() like this:

mail($to, $subject, $body, $headers, '-f'.$returnAddress);

where $returnAddress is the same as your From: address.

It's not guaranteed as some systems flag the fact that you've used the -f parameter as a spam indicator.

In any case, you're far better making life easier by using PHPMailer to do the job
