Should the high load continue, then the connection is discontinued and the sender IP address is placed on a temporary blacklist.<\/p>\n<p>Technically, this task is performed by the <a href=\"https:\/\/www.retarus.com\/tech-products\/retarus-email-security\/#top1\">Directory Filter<\/a>, which already provides options for throttling traffic. What\u2019s new is that we now also feed you information regarding which emails have a spam probability of 100 percent.<\/p>\n<p>As more spam is now already rejected at the Directory Filter level, less spam ends up in the dedicated <a href=\"https:\/\/www.retarus.com\/tech-products\/retarus-email-security\/#top3\">Retarus-AntiSpam<\/a> filter, and consequently in quarantine. As previously mentioned, this is no reason for our customers to be concerned. There are only fewer messages marked as spam in quarantine because more spam from clearly untrustworthy IP addresses has already been detected and blocked by the Directory Filter upstream, meaning that it hasn\u2019t even reached the point at which it would be analyzed by AntiSpam. We find that <a href=\"https:\/\/www.retarus.com\/blog\/en\/spam-wave-online-fraudsters-bank-on-stock-market-manipulation\/\">in times of massive volumes of spam<\/a> \u2013 our systems are currently logging 3 to 4 times the volumes that we were registering at the beginning of the year \u2013 this is certainly good news.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.retarus.com\/blog\/en\/wp-content\/uploads\/sites\/22\/2017\/05\/e-mail_security_overview_new_1280px.png\" alt=\"Retarus E-Mail Security Overview\" width=\"1280\" height=\"1484\" class=\"alignnone size-full wp-image-2159\"><\/p>\n<p><a href=\"https:\/\/www.retarus.com\/products\/retarus-email-security\/\">Retarus E-Mail-Security<\/a> is a comprehensive service for email communication free of virus and spam, offering a wide range of functions including our <a href=\"https:\/\/www.retarus.com\/products\/retarus-patient-zero-detection\/\">new Patient Zero Detection<sup>\u00ae<\/sup><\/a>, which discovers infected emails that have already been delivered to email inboxes, meaning that your company can safeguard itself against the high costs which may result from a successful attack.
