Bug #11628: Net::SMTPServerBusy is not behaving according to documentation

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]

[rupert (Robert Pankowecki)]

The documentation for Net::SMTPServerBusy says Represents SMTP error code 420 or 450, a temporary error (http://ruby-doc.org/stdlib-2.2.0/libdoc/net/smtp/rdoc/Net/SMTPServerBusy.html)

However the code for that is:

      def exception_class
        case @status
        when /\A4/  then SMTPServerBusy
        when /\A50/ then SMTPSyntaxError
        when /\A53/ then SMTPAuthenticationError
        when /\A5/  then SMTPFatalError
        else             SMTPUnknownError
        end
      end

so it actually represents any error code starting with 4, including such as: Net::SMTPServerBusy: 401 4.1.3 Bad recipient address syntax.

It doesn't help that different pages in internet list different error codes:

• http://www.serversmtp.com/en/smtp-error
• http://www.greenend.org.uk/rjk/tech/smtpreplies.html

• Status changed from Open to Closed

Applied in changeset git|14b0c94ac38c40459d908fd4c5778efa60e4689f.
