 In the last years the SPAM phenomenon (Unsolicited Bulk & Commercial E-mails) has grown exponentially. Today the SPAM is over the 50% of the total e-mail traffic. In order not to waste time discarding UCE and IBE e-mails, complex filters are required for the incoming e-mail traffic. **SISSA has two filters for the incoming e-mails**.

 ==== SafeMail =====
-**The first filter for the incoming e-mail is SafeMail, a commercial product of Spin** (http://www.spin.it). This software is installed on the incoming e-mail gateway server. This machine is named hermes.sissa.it that is also the Mail Exchanger (MX) for the domain sissa.it. This filter **is applied by default to all the incoming mail** for the domains sissa.it and democritos.it.
