We are having the same issue here

I find solution on other forum to wait future update of the plugin :

I changed the wp_mail() function to mail() and removed $attachments. This is working for my setup with contact-form-7 4.5 and wordpress 4.6. Obviously without attachments.

see /wp-content/plugins/contact-form-7/includes/mail.php (Line 85)

old:
return wp_mail( $recipient, $subject, $body, $headers, $attachments );

new:
return mail( $recipient, $subject, $body, $headers );

Hello,

I went to the same folder that was described and also made the suggested changes. I am still not able to send email via the contact form on the website I am working on. Is there anyhwere else I can make adjustments? Am I missing something?

Thanks for helping in advance.

Any update from the plugin author? I’m holding off updating WordPress core to version 4.6 on 17 of our client sites because they are using this plugin. I don’t want to have to hack the plugin to fix the issue. I’m just looking for an official update as to when we might expect an updated version of the plugin with the fix. Thanks!
