Rails 3: Actionmailer :BCC field doesn't work

The :bcc field doesn't seem to work.

 mail(:to => "xx@xxx.org",
       :bcc => "xx1@xxx.org",
       :subject => "Welcome to My Awesome Site")

开发者_如何转开发I want to pass to the :BCC field an array of 100 e-mails to send but this doesn't work even when I pass only 1 value.

Thanks

I just ran into this as well. However, I narrowed it down to my use of SES for delivery. I found this issue https://github.com/drewblas/aws-ses/issues/16

When I used sendmail, the bcc worked just fine.
