 Hello,

 Currently I am developing a wordpress theme with a script to send a
 verification mail using wp_mail(). Since switching to wordpress version
 5.5 my script no longer works. By trying PHP's mail() function it works.
 By reinstalling the version of wordpress 5.4 with the wp_mail() function,
 it works again.
 While performing the debugging, I get the following error:
 [wp_mail_failed] => Array
                 (
                     [0] => Invalid address:  (From): wordpress at localhost
                 )

 Thanks for your feedback
