Address in mailbox given [] does not comply with RFC 2822, 3.6.2. when email is in a variable
Your email variable is empty because of the scope, you should set a use clause such as:
Mail::send('emails.activation', $data, function($message) use ($email, $subject) { $message->to($email)->subject($subject);});
(I'm using SwiftMailer in PHP)
I was getting an error like that when I was accidentally sending a string for $email
$email = "someone@somewhere.com <Some One>";
When what I meant to be sending was
$email = Array("someone@somewhere.com"=>"Some One");
I was accidentally running it through a stringify function that I was using for logging, so once I started sending the array again, the error went away.
Make sure your email address variable is not blank. Check using
print_r($variable_passed);
