I have improved Devel::Tinderclient (the client that powers tinderbox) to support email from systems that do not have and use sendmail.
Tindermail::MailMailer allows you to use Mail::Mailer and SMTP to send email to the tinderbox server or (and preferred) you can use Tindermail::Http to communicate directly over http to the tinderbox server, no email required. Note for those already running tinderbox clients: Tinderconfig.pm has changed in several ways (the sample_config dir and rsync support are gone for the moment and new vars have been added to Tinderconfig.pm) so do not attempt to copy your current Tinderconfig into place. Note to those not running clients: please do! Now that support is available for windows (it will run out of the box with unix2win'ing and brentdax is preparing a zip-file which has already been converted) and for systems without sendmail, please install the client especially on rare OS's. Bonsai is coming too. Once that works the 'guilty' column will be filled in on tinderbox. Zach
