电子邮件不会在带有标题的Wordpress中发送

I'm running a new WordPress website on LEMP on Debian 7, sendmail installed.

I have a custom theme installed which has contact form.

Contact form says email sent but email actually not delivered. I have tried to remove $headers from email, email delivered. Simple php mail function working properly. Same custom theme sending and delivering email through form at Shared host.

Here is part of custom form:

What is wrong with this? can anyone point me out what is wrong or how I can start sending emails?

if(!isset($hasError) && ($correct == true)) {

    $admin = get_bloginfo('admin_email');
    $portfolio = get_bloginfo('name');
    $portfolio_url = home_url();

    $emailTo = $admin;
    $pro = get_the_title();
    $subject = "You have an message for $pro";
    $body = "Hello,

You've received an message from ".$name.", for ".$pro." fun name.

Here are message details:
--------------------------------
Buyer Name: ".$name."
Email: ".$email."
Message: ".$message." ".$CurrencyCode."

Message: ".$message."

---------
".$portfolio."
".$portfolio_url;
    $headers = "From: ".$portfolio." <".$emailTo.">" . "
" . "Reply-To: " . $email;

    wp_mail($emailTo, $subject, $body, $headers);

    $emailSent = true;
}

Thank you!

wp_mail has an open bug related to the Reply-To header. Try removing that header only and check if the email is sent correctly. If that's the case, you will have to create a plugin to wrap it or just avoid setting the Reply-To header.
