Clearswift MIMEsweeper for SMTP’s SpamLogic technology, meanwhile, delivers real-time protection against unsolicited email – with an accuracy of 99.5%. Such dependability is achieved through intelligent scanning and categorisation of message source, content and destination to identify spam.

Customers can also deploy the Edge server which is an additional server that is deployed in front of the MIMEsweeper for SMTP product to utilise theTRUSTmanager technology to reject the majority of inbound spam, without having to even see the message contents. TRUSTmanager is a managed reputation database that enables messages originating from senders with poor reputations are quarantined, while allowing other emails to flow freely. The Edge server can also run Kaspersky Anti-virus which could be different from the Anti-virus on the MIMEsweeper for SMTP product, providing an additional layer of AV protection.

Maximum flexibility, easier administration
