SyncServer is a Firefox sync server written in Perl. Mozilla's Firefox sync server, which is written in Python, has many dependencies and is quite tricky to install on enterprise distributions which don't ship with all those requirements. This syncserver implements the syncserver user API and storage API as an fcgi application. It is entirely written in Perl.

.. the spammers use not only fake addresses, in many cases they use existing email addresses they don't own. So sending those confirmation emails produces traffic and fills the real address owner's inbox with useless confirmation requests for emails he didn't send.
Do you know the virus notifications some providers send? Whenever a worm/virus uses your email address - even if it wasn't your computer that's been infected with that worm - you get some stupid messages from providers telling you that "your message did not pass their filters, 'cause they identified the worm blabla.w32.y in that email'".
Now, when someone uses your script and receives a worm, the owner of the (ab-)used email address not only gets those "your email contained a virus" messages but also your confirmation emails.
