When is IMAIL can support the following feature? Tarpitting (recommended) This feature is very effective against Trial and Error Harvesting. Administrators can configure VisNetic MailServer to check for unsuccessful attempts to deliver messages to unknown users by external or local non-existing users. If the number of attempts in a session exceeds the number specified by the Admin, the IP address of the sender will be remembered for that period and no access from that IP address will be allowed within that period. We recommend a count of 3-5 and a period of 60 to 240 min. Please Visit: http://www.deerfield.com/products/visnetic_mailserver/spam_prevention/
