Re: CakeEmail SMTP syntax error 555 (#5.5.4) while sending e-mail to multiple users (with the use of bcc array)

Better triple-check those addresses. It's easy to miss something. Were
all of them validated by cake as email addresses when saved to the DB?

Are you including names as well as email addresses? Maybe something's
wrong there.

And check the server's mail log. That should show you where in the
list of addresses the failure is occurring.
