Which mail servers and operating systems does MWES work with?
Windows: Use any Windows mail server (Microsoft Exchange 2000, 2003, 2007, 2010, 2013, SmarterMail, IMail, Communigate Pro etc.
Linux: Any MTA such as Sendmail, Postfix, QMail, Exim etc.

How does MWES work?
MWES works as a proxy, meaning it sits in front of your mail server collecting and processing all incoming mail. You will notice a significant reduction spam along with reduced load on your mail server when MWES is installed and working.

Since MWES sits in front of your mail server listening for email on SMTP port 25, it then passes any good email on to your mail server on Port 26. You will need to configure your mail server to listen for email on Port 26.

MWES will then quarantine any incoming spam where it can be viewed/rescued conveniently in your web browser. See more info

What is the performance and spam catch rate like?
MWES is muti-threaded, so it takes advantage of multi-core processors. Running on Linux with 2 core cpu, 2 GB Memory, 150GB HD, easily processes 4000 emails per minute. See recommended/minimum specs


What are best practices for blocking spam?
You should see spam blocking rates of over 99%, especially as MWES adapts to the spam you receive. But out of the box MWES should block around 95% of spam

To increase this and filter the remaining spam read these steps
1. You may want to add common spam domains or FROM email addresses using wildcard patterns to the blacklist. These will become apparent over time. eg domains like *@*.ninja
2. You'll want to enable Bayesian Filtering. This type of filtering learns from emails you decide are good and bad and is the last filter to be used. It will clean up almost all remaining spam.

There's not too many reasons to use the Whitelist unless you're having issues receiving email from a user or domain. ie. Their server doesn't support Greylisting, or they've been added to external blacklists.

Can you tell me more about each filtering mechanism?
The Frequently Asked Questions have a summary of each filtering mechanism and the order of filtering.

What is greylisting?
Greylisting is an effective tool to stop spam by sending a temporary fail back to the sender of the message. If the sender is sent via a valid MTA, the message is re-sent and MWES will let it through. If the message is not sent from a valid MTA it is not delivered and left in the MWES greylisting quarantine area. If a company has a valid SPF record, then email from that company will bypass greylisting.

Greylisting and SPF are enabled by default in Settings >> General

How can I setup daily/hourly blocked spam digests for my end users?
The user guide has comprehensive instructions on setting up digests for end-users.

Can I make further changes to configurations not listed?
Yes, you can make some more fine grained changes by altering options in the config file (Linux) or Registry (Windows). See details on further configuration options.

Where can I learn about the latest features?
