hello everyone
I am getting the following message when trying to send an email from the email_sending event server
C:\xampp\htdocs\vendor\symfony\mime\Address.php(54): Email “” does not comply with addr-spec of RFC 2822.
The error means there is no “from” or “to” email address, you may double check your email settings.
If you use code to change from/to in the server event, double check your code. You may also post your code for discussion.
