Measures to avoid spam when sending and receiving e-mails

Swiss company Infomaniak - which hosts thousands of websites and e-mail servers - has published an article on its blog describing the various measures taken to prevent the transmission of unwanted e-mails (unsolicited advertising, scams, messages accompanied by viruses, etc.), both when receiving and sending messages.

This article reveals the unsuspected complexity of the task, and underlines the importance of hosting your mail server with providers - preferably Swiss - who can deliver quality services.
