Error when sending via Amazon SES SMTP

[xaralis]

There is problem with sending via Amazon's SMTP. The thing is that when you try to send to an address which is blacklisted (and that unfortunately happens from time to time), it is not reported as SMTPRecipientsRefused. Instead, it is raised as normal exception with a following string in it's message: "Address blacklisted".

It would be nice if mailer could handle this since it effectively prevents the newsletter to be marked as "sent". Error statuses are not considered final and mailer tries to send it again and again with the same result.
