When trying to send mail through my mail server via net/smtp.rb I'm getting the following error. Authentication is made, but mail is not delivered.

When I comment out line 936 of net/smtp.rb (raise SMTPUnknownError, "could not get 3xx (#{res.status})"), I receive the following error but in spite of it mail is successfully sent.
