AHBL  has been closed, so anyone using the list needs to remove it

the smtp server requires the SSL on the SMTP connection, so unless you are useing SSL it will fail

I´m using the exchange 2010 smtp conector.

Now,  Exchange does not send messages to most foreign destinations. Sends only to gmail mailboxes and other few destinations (English)

below I sent you the error message I get from hotmail
