When using PHPMailer to send email to BCC'd addresses via Amazon SES, SES returns the error below.
554 Transaction failed: Invalid email address undisclosed-recipients:;.
This only happens when there is no address specified in the "To" field and it is filled with "Undisclosed-recipients:;". I have tried sending email with just an address specified in the "To" field and it works fine. When sending email with an address in the "To" field and addresses that are BCC'd, it also works without error.
This is the PHP code i'm using to add each email address as a BCC, $Addresses is an array containing email addresses, without keys.
if(is_array($Addresses))
{
foreach ($Addresses as $Email) {
$Mail->AddBCC($Email);
}
}
This is the output from PHPMailer.

I have also found that a few people get this error when using Postfix with SES, but I am yet to find how they resolved the issue.
I've seen this happen if an email in the 'BCC' matches an email in the 'TO' field.
