drupal_mail() and names with apostrophes When using drupal_mail to send an email, I get errors when display names (not emails) contain apostrophes in the "To" field.

For example, referring to drupal_mail() documentation, email addresses like "Another User &lt;anotheruser@example.com&gt;" are valid. "Another User &lt;anotheruser@example.com&gt;" validates perfectly, but "Another O'Neil &lt;anotheroneil@example.com&gt;" fails.

Do I need to change the last name to ONeil instead of O'Neil, or can escape it somehow?
I have also tried ""Another O'Neil" &lt;anotheroneil@example.com&gt;" without success.


Setup: Ubuntu 11.04 LTS 
Drupal Version: 7.x
Mail Service: Amazon SES
Additional Mail Modules: "HTML Mail" and "Mail System"
I assume a few things: 


You have no exotic mail transport installed, having Drupal fallback to phps' mail()
You deliver the mail trough a unix system. Windows deals differently with mail.


Digging into RFC2822 you will find about escaping " and some other characters. 

The solution then presents itself as

$to = "\"Another O'Neil\" &lt;anotheroneil@example.com&gt;";
drupal_mail('contact', 'page_mail', $to, language_default(), $values, $from);

print $to; #=&gt; "Another O'Neil" &lt;anotheroneil@example.com&gt;
