Making a recommendation is difficult, because every site has a different email profile.<br />
I usually avoid products from the AV vendors as I find they cause more problems than they resolve. <br />
Cloud based can work for some clients.<br />
I have also had good success with GFI ME and Vamsoft ORF on other sites. <br />
I have also had them fail on me.<br />
<br />
Get a shortlist based on the price you are prepared to pay then evaluate. DO NOT buy on reputation alone. Quarantine everything until you are confident with the problem.<br />
<br />
The key criteria I find is checking what it is blocking, which it shouldn't be. All spam filters can block 100% of spam, if you don't mind them blocking the legitimate stuff as well.<br />

Although defence in depth is always good, I prefer to not run any 3rd party anti-spam solutions on Exchange, I have found it much more reliable to run an external spam filter, these range from efa <a href="https://efa-project.org/" rel="ugc">https://efa-project.org/</a>&nbsp;as a Linux appliance, to fully hosted &quot;cloud&quot; offerings

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
