Mail.Ru launches new spam filter and spam analytics department
Mail.Ru officially launched a new anti-spam system. Until today, its testing was carried out, and the result was very positive: the number of spam complaints from users decreased five times.
The new spam filter works on the basis of old technologies used for several years, but it has been significantly improved. The solution was developed by Mail.Ru technical specialists in close cooperation with Kaspersky Lab. The core of the system includes the anti-spam signature database, which is constantly updated and changes depending on the current situation.
The system checks not only the entire flow of incoming correspondence, but also internal traffic (that is, letters from Mail.Ru to Mail.Ru) and outgoing messages. On fuzzy grounds, as well as using a database of signatures and user complaints data, dubious mailings are allocated from the stream. Statistical information about them and about system solutions is displayed in the administrator console of the Mail.Ru team of analysts, working around the clock seven days a week.
The team of spam analysts is another innovation in the organizational structure of Mail.Ru. They control the progress of the system and quickly make changes, adapting to unwanted mailings. The time of analysis and reaction to each new newsletter is only a few minutes.

It also uses its own and public blacklists of "unreliable" senders - open relays and spamming subnets.
“As a result of testing our new system, we received very positive results,” says Mikhail Meshchansky, head of the Mail.Ru anti-spam development team. - The number of user complaints decreased significantly. Efficiency is noticeable in other ways. For example, the use of blacklist boxes has plummeted. ”
Currently, the new anti-spam system blocks about 20 million spam emails per day. About 80 million more is delayed earlier, at the stage of filtering open relays and spamming subnets.
