 * Hello,
 * First of all, thank you for your great plugin. I am using it a couple of websites
   and it works great.
 * However, I have the following annoying issue:
   I want to have the reply email 
   address to match the one entered by the visitor/user who submitted the form. 
   For the purpose, I am using the following header with the fields from the submitted
   form:`Reply-To: [first_name] [last_name] <[email]>`
 * It unfortunately shows an error with exclamation mark in a couple of places:
   
   1. [https://prnt.sc/8rM2BCbA58u7](https://prnt.sc/8rM2BCbA58u7)2. [https://prnt.sc/NpwDjxzXgqHT](https://prnt.sc/NpwDjxzXgqHT)
 * Please let me know if this can be fixed. Thank you!

   This will do the job in my case (in wp-config.php):`define( 'WPCF7_VALIDATE_CONFIGURATION',
   false );`I am closing the Support forum thread.
