NAME

       Mail::Milter::Wrapper::DeferToRCPT - milter wrapper to delay failure returns

SYNOPSIS

           use Mail::Milter::Wrapper::DeferToRCPT;

           my $milter = ...;
           my $wrapper = new Mail::Milter::Wrapper::DeferToRCPT($milter);

           my $wrapper2 = &DeferToRCPT($milter); # convenience

DESCRIPTION

       Mail::Milter::Wrapper::DeferToRCPT is a convenience milter wrapper which defers any error
       return during the "connect", "helo", and/or "envfrom" callbacks to the "envrcpt" callback.

       Many broken client mailers exist in the real world and will do such things as
       instantaneously reconnect when receiving an error at the MAIL FROM: stage.  This wrapper
       ensures that errors are never propagated back to the MTA until at least the RCPT TO:
       phase.

       Errors in "connect" and "helo" will apply to the entire SMTP transaction.  Errors in
       "envfrom" will only apply to that particular message.

       This wrapper can also be used to enhance logging.  Though the contained milter may wish to
       reject a mail in progress, it may be useful for logging purposes to capture the HELO
       string, sender, and recipient addresses of each attempted mail.
