Address in mailbox given [] does not comply with RFC 2822, 3.6.2. when email is in a variable

Question

I have a correct email address. I have echoed it, but when I send it, I get the following error:

 Address in mailbox given [] does not comply with RFC 2822,          


        

Answer 1

(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 ";

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.
