Simple - Single Focus - Excellence In Spam Filtering

Blooming awesome. I am an admin /postmaster for around 20 domains. MXGuardDog is being rolled out across them after we tested for over a year with a couple of difficult recipients (who were getting thousands of crappy emails per month) They are not technically literate yet the MXGuard Dog process worked for them.

Pros:

It just works - end of story. It has a simple setup, it has been utterly reliable nad it does an excellent job of weeding out crud - while allowing you to whitelist wanted addresses and domains. It also has country filtering - which removed a ton of crud immediately. I have used this product for over 10 years and am implementing it across the domains I host mail for. I also love the fact that if my server was to go down, they will catch and store mail long enough for me to get the issues resovled - so no missed mail.

Cons:

I am always more comfortable if I can pick up a phone and call someone - but this is a low risk factor - as if MXGuardog were to ever fail, I would just switch my mx records and everything would work again (with more spam).

Reasons for choosing MXGuardian

Simplicity, price, control. We wanted quick and effective fix -not a technical mission to achieve.

Completely Satisfied!

MXGuardian turned out to be the best choice for us. The product is solid, even at a lower subscription. Users find the interface intuitive and it's cut down on managment time for our internal tech team. Support is always helpful and we're very happy to be using MXGuardian for our email protection service.

Pros:

We were in a meltdown regarding our Spam and mail security due to a targeted attack from the outside. Our previous system was barely protecting us at all. MXGuardian techs helped us get set up and configured to minimize the DOS attack and give us back control of our systems. They have been responsive to all of our questions and are making sure we are getting the most out of our subscription!

Cons:

Sometimes it's difficult to understand the organization of the countries when looking to block or allow specific traffic, but I blame my geography grades for that. The language blocker is a nice bonus!

Reasons for choosing MXGuardian

Cost was a big factor for us, also responsiveness of the seller. We were able to get immediate results with MXGuardian

Reasons for switching to MXGuardian

No control over DOS or spear-phishing attacks

The product is right on point.

Overall the best value I've found for what I needed. I searched for weeks before I found this and have been nothing less than happy with the decision. My customers are protected and have the same features as the higher priced alternative I was using.

Pros:

Inexpensive so I could replace a previous product that constantly raised their prices each year. Selecting the features I needed were available so I didn't have to pay for features I would not be using. Easy to understand from both the end user and the administrator points of view. Equally effective and adjustable like the previous high priced product I was using.

Cons:

Some of the administration fields could use better or more explanation. Maybe some inline tooltips on some of the form fields.

Reasons for choosing MXGuardian

Price, features, ease of use.

Reasons for switching to MXGuardian

Barracuda too expensive. Raised prices every year for features I did not need and were not able to exclude from pricing.

MXGuardian cannot be beat for the features at the price point, a fantastic product.

Fantastic, i've had to reach out to support a few times over the years, and they have been great, and it's usually something i've done or not done that has been the issue. You just set it up, and it just works. i don't think any product out there could filter all SPAM, but MXGuardian does a pretty great job.

I've been using mxguardian for over 5 years and because from what i remember, the simplistic but very effective features just cannot be beat for the price.

i found that the in-house mcafee solution was just getting too difficult to mange and maintain for exchange 2010 at the time, and when we swapped to Microsoft 365, it was as simple as just changing the IP address.

MXGuardian nearly unbeatable as a standalone E-mail filter.

All in all this is a good product and not over complicated or cluttered, does what it should as it should.

Functionality

Pros:

The ease in adding to allowed or blocked lists, the ability to see reports of blocked items 2 times daily. The ease of releasing false positives. The 30 day archive is a great feature. The ability to set settings strict or be able to loosen the restrictions.

Cons:

As of now meets all our needs, maybe a weekly summary report of all sub accounts, that details any changes amount filtered etc.

Reasons for choosing MXGuardian

Ease of setup, ease of use, price for feature. MXGuardian just works and is not full of crap you will never use. It filters spam and viruses very well. And has a easy release function instead of a Global block list you can't get the sender off of. ALL SPAM FILTERS should allow you to release legit mail that is clean of viruses. MX allows you to do just that. Great product.

Reasons for switching to MXGuardian

Onlymyemail had a huge outage and no support, just stopped working one day and then they disappeared. We had already made the move before they even fixed the outage.

I can't stress enough how efficient and quick the MX tech-support and customer service have been when I have needed them. I have posted on social media that I recommend this software highly to anybody with business emails.

Pros:

I couldn't be happier with MXGuardian. They block virtually all spam and I find very few emails that should have gotten through to me. In a world with questionable tech support and customer service, MX is five-stars, not that I need support all that often because they're extremely reliable.

Cons:

I really have no significant criticisms. I suppose that 100% would be better than 98% or 99% but that's almost impossible to attain.

Pros:

A move from the Google Postini service was required after Google over complicated the product. MXGuardian does the job simply, reliably and is very easy to configure and use on a day to day basis - plus it's considerably cheaper than many inferior alternatives (including Google).

Cons:

I'd like the ability to be able to simply use MXGuardian as an outbound smarthost which would allow MXGuardian to learn addresses that our organisation sends to (as they're likely to be 'good' senders of return traffic).

Reasons for switching to MXGuardian

The previous product was no longer fir for purpose.

Hi Jon, Thanks for the great review. Just so you know, we do offer an outbound relay service. Just email support@mxguardian.net and we'll help you set it up.

In a world of chat bots - there is a real solution

I've needed support a few times - and it's always a person that listens and tries to figure out a solutions - not read a script. When a support agent is reading a script - they are impersonating a bot - that is NOT what happens here.
