Mail not working

Problem

mail is not working

Cause

multiple, ‘From: ‘ header is incorrectly formatted and non-standard php environments have issues with the mail function. Mailing in these environments can often be solved by using a plugin like ‘WP Mail SMTP’ (https://ww.wp.xz.cn/plugins/wp-mail-smtp/) but this requires the use of the wordpress wp_mail function by the plugin.

Solution

Edit ‘ai-responsive-contact-form.php’.

1. lines 459, 461 and 464:
   replace the ‘mail(….’ function calls with ‘wp_mail(…’
2. line 378, change

   $ai_headers .= "From:".get_bloginfo('name')." ".$ai_emailadmin."\n";

   to

   $ai_headers .= "From:".get_bloginfo('name')." <".$ai_emailadmin.">\n";

3. line 449, change

   $ai_admin_headers .= "From: ".str_replace(' ', '-', $ai_name)." ".$ai_email."\n";

   to

   $ai_admin_headers .= "From: ".$ai_name." <".$ai_email.">\n";
