I've tested a decent number of anti-spam gateway products in the past, and honestly I just haven't been satisfied with them. They are either inaccurate, hard to use, hard to set up, or worse. Thanks for making this great product available.
...on my test mail server it appears that MWES places an extremely low load on the server. It really is quite impressive what you have achieved with it.
Block spam before it gets to the server
MailWasher Enterprise Server works as a proxy, so it sits in front of your mail server blocking and denying spam from getting to your mail server and users. Ultimately your mail server will have less work to do because it's only receiving legitimate email.
With its easy to use web interface, MWES is simple to setup and use for administrators and users.
Since MWES sits in front of your mail server and has extremely low system resource usage, no extra hardware is required and emails never leave your network. It only takes around 10 minutes to install and configure, or just ask us and we'll do it for you.
Let your users manage their quarantined email
With spam quarantine facilities, users can be sent a daily (configurable) digest of quarantined email and rescue blocked messages from within the digest email. Users can also quickly search, view and unblock any email via their browser.
Alternatively, the header of the email can be marked, delivered and then filtered by the end users email client.
Intelligent spam tools
Advanced spam detection technology and tools do all the hard work for you by automatically quarantining spam emails.
From a simple whitelist (IP or email), blacklists (IP or email), greylisting, bayesian filters, real-time spam signature updates, RBL's, Trusted IP's to advanced custom filters, MailWasher has you covered.
Comprehensive administration tools
MWES reports daily statistics of how much email is being blocked and by what spam tool. The Email screen lets you further drill down and find why an email was blocked.
Other administration tools let you auto generate user accounts for end-users to view their blocked spam, send rejection notices, let users access spam digests for other aliases and report spam.
Quick Answers to Common Questions
Which mail servers and operating systems does MWES work with?
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.
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 mop 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?
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 the configuration 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?
You'll find these in the Version history page.
