gmail (Score 1)

At home with a private domain-name, I forward all my email to gmail, let gmail do the job of filtering, and download it after that. (1300 spam messages in 2 days) After that I redistrubute the mail to my family-members. At the office we have a provider who checks our mail for spam, so there is a spambox centralised at our provider. ( > 3000 a week) This is also our fallback, just in case our company email fails. At the office we have a dmz and a server with trend micro, which filters spam. Also a large quarantaine area with quarantained emails. Even then there is spam reaching the users. In the local network of our office is an exchange server. The users are working with outlook and have the opportunity to make filter-rules for spam. When users know for sure there is an email sended and it has not reached their email-box, we can connect to the quarantaine-area in the dmz, search for the email and release it to the user. So the positive effect of all these things is, that I can use my time for orther things. (games and so on...)
