### "Xeams is awseome!"

September 26, 2019

4.0

Spam was a big throuble to us, when enable xeams, its easy to work and support our users. For now, we are using as Outgoing SMTP only since Proxmox Mail Gateway offer more than Xeams in OpenSource edition and have a better support, forum and better license cost.

Pros

Single to install, use and maintenance. A great platform to manage email gateway with good integration, as OpenLDAP and Ms Active Directory.

Cons

Poor forum (design, responses, infromations), Very limited free options and customization reports are very complicated or limited.

Reason for choosing Xeams

Easy to use and maintenance. But, as i said, we are using Xeams only in outgoing features. For incoming, we are using Proxmox Mail Gateway.

Simple! Zimbra antispam doesnt work.

Thank you very much for your feedback. Could you please tell us a few features you see missing in Xeams but are there in Proxmox. As far as support goes, we offer free support (telephone, email and forum) even for community edition.

### "Review"

November 15, 2019

5.0

Over all we have used Xeams for a few years and we are content with it. Its features match its pricing and is fairly easy to use.

Pros

I like the software seems stable and customers do like the daily emails about blocked traffic. But they do get confused thinking they are still receiving these emails even though those emails do not reach their inbox. Up dates are regular and software is stable.

Cons

I would like to see more customization themes to match our company. Green is not part of our company color schemes. I think that the spam AI could be better as quite a few emails do not get through and some unwanted mail gets through. Also the Xeams service crashes some times and will not restart on its own even though its set to in windows services. We use to use Smarter mail they have an amazing anti spam AI that seems to work perfect and blocks exactly what you want and you revive exactly what you want. But you also pay much more for it than Xeams that is why we switched.

### "Small Business Go To"

December 3, 2019

5.0

As a consultant for a number of small businesses with few employees, the business needs to focus on day-to-day functions and not have to sift through the large quantities of spam that is invading our communication space and still let the valuable emails through. Xeams is the right answer allowing the user to decide which are the emails they want to receive by white-listing the emails. In three of my install cases, we are seeing 80-85% stop rate on spam and frustration calls from clients have been reduced from 4-5 per week to 1 or 2 a month. Great job Xeams!

Pros

The configuration of this software for old-school in-house email servers is very simple yet has all the features to make a robust spam detection system. File organization is intuitive and easy to customize. This software just works.

Cons

I started using this software as a solution for small businesses to utilize a free spam detection utility. It was disappointing to see the open-source usage move to a pay-to-play but it is understandable that to keep the software active and up to date. pricing could be a little lower for long-time users

### "Great for backing up emails from online email providers. I use to back up Gmail and Aol mail."

November 22, 2019

5.0

Xeams allows me to have a business presence and I finally figured out how to setup POP Fetcher that the support staff could not setup for me, so now I am backing up Gmail and AOL on my server and I get the benefit of the spam filters, and since I also figured out how to connect CLAM AV I get a virus checker also.

Pros

Anti Spam and Virus filter. I have found several attacks that gmai and AOL missed

Cons

That the unlimited version was not grandfathered for users that had it prior to making it a paid version. Having a WEB client to view mail in the mail box would be nice.

Reason for choosing Xeams

The ease of install, the PROMISE of unlimited users that included filtering every unlimited free email box. Now it is limited and that really sucks. I am not planning to run a huge company server just me one other and backup my web accounts so that I have the features of filtering that are unmatched. But I may need to find another product(s) sooner then later to replace this

### "License vs. "free""

March 27, 2019

4.0

The reduction in SPAM, etc. is on par with other paid for services. Server services resource demand is fairly light overall.

Pros

Powerful if you are willing to dig in and tweak. Out of the box works well, over time gets better and better. Paid for value is good, a big difference from running unlicensed. I think that with effort, I stress that, the unlicensed version could be just as proficient. The time saved by purchasing licenses is worth it to me. Tech support is responsive. I like having in house control of my IT services.

Cons

Unless you are a full time email guru the documentation could be a bit more illuminating. A virtual configuration tutorial A->Z to show everything that should be done as a basic example focusing on the less obvious options would be good. I think it is all there in the documentation but if you don't know to look for it.... I don't generally have time to read an entire manual before I implement. May say more about me though.

### "Feature rich and easy to use"

November 8, 2019

5.0

We can be a little more confident that emails that could literally bring to company to a halt are stopped in their tracks. Also the end user gets a daily report saying what potential spam has been stopped, we have it set so they need to contact our IT department to have any messages they think they need from that report released. This then offers another level of security as those suspect messages would be reviewed by our IT support first.

Pros

The ease of configuration and the speedy support you get. It is very good at learning what is spam and what is not, It shields the company and the end user from potential risk. Options like the Sandbox and the reports are a nice feature as well as the ease at which you can review and release emails.

Cons

I would be nice if the antivirus aspect was just built in rather than having to install and maintain that separate but that is only a minor negative.

Reason for choosing Xeams

Features and price.

### "Greatest way to save my time dealing with emails"

November 7, 2019

5.0

Sounds over the top - but in all my years using spam software i love this one and is a pleasure to work with and the staff are brilliant - even with the time difference as I am in the UK

Pros

The speed and ease of use and to be able to admin/use it remotely also

Cons

Nothing much as usually most things I adress are sorted but there is 1 annoying one i am having. if i view an email in spam and it's too wide, there are no slide bars or pinch and zoom available when using my mobile device ( please correct me if i am doing something wrong)

Reason for choosing Xeams

Cost, Speed, Easy, Self Maintaining, Never fails, Always works. Customer service is awesome!

### "Xeams Email Filtering"

November 8, 2019

5.0

I have used Xeams for 4 years now. There is a reason why I stick with it. It works for our needs.

Pros

I really like the amount of customization you can do to it. You can really tailor to the businesses needs.

Cons

Some features that you would think would be available are not. There are some aspects that are not user friendly.

Reason for choosing Xeams

Price and customization.

Switched from

[FortiClient](https://www.capterra.com/p/151916/FortiClient/)

Not much customization and was expensive.

### "Long time user"

November 21, 2019

4.0

Great application and have been happy with it for a number of years.

Pros

Software works very well blocking most spam. I have been using it as my front end to my Linux servers postfix server and both work great together. I am using it for home use, but for a small to medium size company I would have no issues deploying this solution.

Cons

Licensing is a little too much if I had to add another family member. Free forum support is ok, but having no back ground with paid support, I am not sure how well it would work.

Reason for choosing Xeams

I was using a home grown setup of a number of open source applications to do spam, and other filtering. This application is all setup via the web gui and requires very little work to keep it running.

### "The power and features you need"

November 12, 2019

4.0

As a smaller IT company that does a little hosting on the side, we need to find ways to make our money stretch. The one time I had questions of tech support, they exceeded my expectations of turnaround time and the knowledge they shared explaining.

Pros

Xeams is easy to install and has an option to fit any need you have. It has saved me hundreds of hours and thousands of dollars in productivity at a price point that doesn't break the bank. Setup didn't take long to be up and doing its job. Understanding its functionality was a breeze to a less than knowledgeable person.

Cons

When they changed to a paid product on user count. I was on top of the world when it was free, but I understand the need to change. Wish I'd have found them sooner!!

Reason for choosing Xeams

I wanted something local as opposed to cloud based. I know cloud is the wave of the future, but I am not there yet and needed a local alternative

### "Xeams for filtering SPAM email"

September 30, 2019

5.0

Pros

The flexibility of this software is high. It can be configured as a SPAM filter only or as a full email server. It can also act as a secondary email server.

Cons

Some of the configuration parameters are not explained very well. I had to dig around in the forums to find answers to some of my questions and some could not be answered without contacting customer support.

### "Happy Xeams customer for almost 7 years"

March 6, 2019

4.0

Xeams has been and continues to be an excellent SPAM filtering tool. We host email for a dozen or so client offices, and I love the ability to have one central Xeams server for all our clients, but they each have their own individualized company portal, as well and individual logins for each person at those clients. Our clients have been very happy with the SPAM filtering results, as have we (we use Xeams for our own email filtering as well).

Pros

The first thing that attracted me to Xeams is it's platform agnostics - I don't need a Windows server to run it on. Having used it all these years, what I find I like best is it's effectiveness.

Cons

Some of the lesser-used configuration options are a bit involved to implement, like installing SSL certificates.

### "Integration and transparency"

November 17, 2019

5.0

As it is used for personal and family business it exceeds my needs and feels like premium and well maintained product.

Pros

\- As Multi Platform software it is unified for setup, which was easy and straight forward - Good filtering options for both beginners and Advanced users/administrators - Ability to install on QNAP NAS which makes it transparent and easy to maintain

Cons

\- Subscription policy as I use it in small company up to 10 Users where higher license was needed. A more dynamic busniss plan would be more welcome

Reason for choosing Xeams

XEAMS was easier configure at time, better GUI and easy of use.

### "Xeams as a Front-End/Proxy Server"

November 15, 2019

5.0

We run Xeams in a cloud-based VM and it works very well with our on-premise Exchange server, filtering incoming and DKIM signing outgoing emails.

Pros

Clean web-based management. Pretty much 100% reliable. Daily Spam reports. Reliable. SSL integration with Let's Encrypt. DKIM support for outgoing email.

Cons

Licencing model. Its quite heavy on memory usage (configurable, but likes 3Gb), We have clear emails peroidically as it retains good and bad email folders with the emails in them. It would be good if we could set a (say) 28 day retention policy.

### "the best spam filter"

November 18, 2019

5.0

Pros

it can be used as an email server and an excellent spam firewall / it filters 99.9 % of junk and infected emails with clam av / if is installed in a dedicated machine and used as spam firewall the actual email server is not overloaded with useless emails and protected because the emails will not rich the server.

Cons

Encryption is not available less then 50 users license / for small businesses is not affordable and efficient . So the small businesses are looking for another solution and could give up on Xeams.

November 10, 2019

4.0

I have used the product for several years and have promoted to other companies outside of my test environment. I would definitely recommend for smaller companies as it is feature rich for the cost of the product along with continual product improvements

Pros

several features for the cost ease of use adequate reporting continual improvement

Cons

server restarts tend to hang from the gui when doing so from the home page with no indication why it is hanging

### "Simple, Efficient Email Security"

March 27, 2019

5.0

Emails landing in people's inboxes are almost entirely spam-free. On the rare occasion where a valid email is considered spam and quarantined, the notification and subsequent retrieval is swift and hassle-free.

Pros

The ease of setup is excellent but beyond that ease is the sophistication to refine and enhance the control.

Cons

Nothing particularly springs to mind. Whatever criticisms I might suggest, they are firstly minor and secondly insignificant compared to the benefits the software brings.

November 11, 2019

5.0

I have a small company and, Prior to Xeams, I could not find any other mail server that was within my limited budget. Now, I am pleased to be able to offer my web clients their own email linked to their domains.

Pros

The customizable spam filters that "learn" as they're used.

Cons

Once it was free; now it is not. However, I get it. A great product and its team must be supported. The other thing I wish was available is a web-based interface for clients to use.

November 7, 2019

4.0

Pros

Xeams is pretty much a configure and forget product. You set it up and get it running and it just works. I rarely have to go into and troubleshoot issues.

Cons

Sometimes it's a bit hard to find where some of the settings are. Simply because there are so many.

Reason for choosing Xeams

Xeams was a less expensive option than say barracuda. And it has the options we needed and was something we were comfortable using.

Pros

The software is easy to use and the web console allows access outside of the Office. The Filtering is easy to use and has been reducing the number of spam emails our company receives for the past few years.

It's pretty good. I don't know compared to other products but it seems to still let quite a bit of SPAM through

Pros

Cons

I do not like how users are handled for bypassing filtering. It is confusing to me.

### "The Best Spam Eliminator"

November 11, 2019

5.0

I have recommended Xeams to dozens of my clients and installed it on their mail servers. It has eliminated 99% of all my spam and my clients are very satisfied with their results as well. It takes a few days (7 - 10) to train the Bayesian learner, but if you are diligent in identifying false positives and negatives during the initial training period, the software accuracy is great. Every correction increases the accuracy. I receive at most 3 false identifications per week. I will continue to use it and recommend it to my clients.

Pros

The installation and configuration is extremely easy. The accuracy is the best in the industry.

Cons

Initial set up the filter rules, but, unfortunately, it must be done. Due to the nature of my business. I have a lot of abnormal rules.

March 6, 2019

5.0

Started out as a free user, ended up liking it enough to pay for it, even though it's just for personal, non business use. I used to use GFI MailEssentials but it was far too expensive for non profit purposes.

Pros

Easy to deploy, easy to maintain, uses minimal resources

Cons

Searching for specific emails is not as obvious as it could be If there was a better way for end users to approve/block emails
