Recently a critical exploit was discovered in Web mail application named RoundCube, which sadly was used on this server (see more info here). By using this exploit one could easily turn your Web server into a SPAM-ing relay. And if the server is not powerful enough you could expect a DOS attack by receiving thousands of postmaster and/or bounced e-mail messages. Luckily the fix is available already, so if you are using RoundCube too, then hurry up patching it!
