Similarly to transport agents, anti-spam agents are assigned a priority value. Anti-Spam Mailbox AgentsĪnti-spam agents are usually enabled on mailbox servers when an organization does not have an Edge Transport server or some sort of third-party anti-spam filtering appliance. It handles SMTP mail flow for the organization, performs message categorization, content inspection and does queue messages locally.įor these reasons, anti-spam agents in Exchange 2013 run on Mailbox servers. On the other hand, the Transport service, which runs on all Mailbox servers, is almost identical to the Hub Transport server role in previous versions of Exchange. However, remember that CAS servers now act as a stateless proxy for all inbound and outbound external SMTP traffic, it does not inspect message content and does not queue any messages locally. With the server role consolidation in Exchange 2013, one might expect the anti-spam agents to now be installed on the Client Access servers (CAS), which run the Front End Transport service, since this service is the first point of contact for any inbound e-mail to the organization. It uses transport agents to provide anti-spam filtering with built-in anti-spam agents available remaining relatively unchanged from Exchange 2010.

As to the latter, first there was Microsoft Antigen for Exchange 2003, then Microsoft Forefront Security for Exchange Server (FSE) for Exchange 2007 and finally Microsoft Forefront Protection 2010 for Exchange Server (FPE) for both Exchange 2007 SP.Īs we all know, in September 2012 Microsoft announced it was discontinuing further releases of all of the Forefront suite products, with FPE support expiring December 31, 2015.

As such, all these features were typically complemented either by using anti-pam/anti-malware third-party software or appliance, or Microsoft’s own software. However, although this provided a good level of protection, there was never in-built anti-malware protection for some reason.

This meant that small organizations that did not have the means, capabilities or enough e-mail volume to justify the cost of installing and maintaining a full perimeter network together with an Edge Transport server, could still take advantage of almost all its anti-spam capabilities. All these features could also be enabled on a Hub Transport server, with the exceptions of connection and attachment filtering. With Exchange 20, Microsoft further improved Exchange’s anti-spam capabilities by providing connection filtering, content filtering, attachment filtering, sender ID, sender/recipient filtering, sender reputation and IP allow/block lists out of the box on an Edge server. IMF, first released in May 2004 became an integral part of Exchange 2003 in SP2.
