ANTI-VIRUS E-MAIL PROTECTION
All of our E-mail servers employ anti-virus software that scans every message for known viruses before delivery. If a message contains a virus, it will not be delivered, and a warning message will be sent by the system to the addressee about the incident. There are no configuration options - anti-virus software is always enabled for all domains.
ANTI-SPAM E-MAIL PROTECTION
SelfNet E-mail servers use state-of-the-art anti-SPAM software to monitor and prevent Unsolicited Commercial E-mail (UCE or SPAM) messages from being delivered to SelfNet customers. Our software identifies SPAM by using series of comprehensive tests - domain name, URL and IP address "black lists", mail routing and DNS records check, text and HTML content scanning, phrase filtering and Bayesian statistical filters, which use common spam characteristics to identify spam. Words and phrases are analyzed based on how frequently they appear in good email versus bad email, then messages are analyzed in terms of probability of being spam. The engine and its reference database are updated daily.
HANDLING SPAM MESSAGES
However, there is no perfect solution - there is always a slight chance that some legitimate mail will get caught by the anti-spam engine. That is why we provide our customers with flexibility to manually customize SPAM handling for their domains. Once an e-mail message is identified as SPAM, it is automatically placed into User's [Spam] folder on the mail server, and kept there for 10 days. During that time, users can either a) take no action, and the message will be automatically deleted after 10 days, or b) using the WebMail interface, move the message to their [Inbox], so they can be opened and/or retrieved from the server. In addition, Users and Customer Domain Administrators can use "Black & White List" feature, to maintain their personal, or domain-wide lists of legitimate mail senders and spammers.
DISABLING ANTI-SPAM PROTECTION
Although most of our customers prefer our anti-spam engine (which is 95%-97% accurate), there are situations when mailings tagged as spam are actually legitimate. Some examples include computerized mailing lists, popular spam topics and terms in the message body, and even sub-standard e-mail systems used by key customers, causing false identification of e-mail messages as spam. In such cases, we can disable anti-spam filtering for a domain by customer request. However, this action should be the very last resort, as it requires special configuration of your domain on the mail server. It is always better to try to fix the problem with a few senders, then to disable anti-spam engine and leave your domain unprotected.
