|  Open Relay Filter - a DNS blacklist (DNSBL, RBL) based anti-spam add-on for Windows 2000 servers that protects your mail servers from being flooded by unsolicited bulk emails.
 Block Outlook spam efficiently at the source: the Open Relay Filter is an anti spam software for Exchange to perform filtering on the server-side, so you don't need a separate Outlook spam filter for every client. There are two Exchange spam editions of Open Relay Filter, the Standard Edition (SE) and the Enterprise (EE) edition. The Standard Edition can be configured very easily, however it offers less Exchange spam filtering tools and a limited set of configuration options. If you are looking for a more flexible, more effective Exchange spam blocker or anti-spam software for Outlook, we recommend that you have a look at the Enterprise Edition. This Exchange server spam edition was designed with performance and flexibility in mind and this makes this edition an enterprise-level solution. Our Exchange 2000 anti-spam solution to stop spam is to monitor the SMTP sessions on your mail server and stop mail coming from so-called "open relays" and other spam sources listed by DNSBL (DNS BLacklist, also known as "black DNS lists") spam source databases. The ORF exchange server spam filter also supports blacklisting senders, IP addresses, disabling local mailboxes and filtering mail coming from fake, non-existing sources for efficiently blocking exchange server spam while not interfering with the mails from your daily work. This method of spam filtering is supported by many popular mail servers in the industry, such as Sendmail, Exim, Procmail, qmail, iPlanet Messaging Server or Postfix and used is by large ISPs who protect their users from spam. ORF is therefore the ideal Exchange spam filter for completely protecting your Microsoft environment from drowning in spam mails, making a separate Outlook 2000 spam filter unnecessary. It is therefore a highly recommended Microsoft Exchange download add-on that can be summarized as "anti-spam Exchange", "blocker Outlook spam", "Exchange 2000 spam" and "spam block Exchange".OutlookSpamFilter DNSBL ExchangeSpamFilter Outlook Spam Filter DNSBL , Exchange Spam Filter Microsoft Exchange Download .
