SpamMarshall features include Real-time monitoring, Usage of content filters, Grey Listing, Anti Phishing, SPF Check, PTR Check, Incoming emails rate control, Domain type checks, Domain age check to name a few.
The best thing about this software is that it has all in one solution for email security including spam filtering which makes life easier when you have multiple domains with different requirements like blacklists etc.. It also provides great reporting options so we can easily monitor our domain's performance as well its growth over time along side other reports provided by spamproject itself such us number/percentage report or even customised ones if required! I wish there was more…
It's very easy to set up for our use case where we are trying to keep spam out of our inboxes. The support is top notch as well! They're always willing to help you troubleshoot or figure a way around any issues that crop up with their product. I would say it took us about 2 weeks from first contact through implementation until reaching full production status. We started using them in May 2018 so there was some lag time during testing/implementation but they were super responsive throughout this
Pros
Ease of use, flexibility & ability customize workflows specifically tailored towards your business needs (elections)
Cons
Some more configuration options available via web interface instead native app
I like that it's very easy to set up rules for my mailserver and also that you can easily filter out spam. It seems not to be as good at filtering phising messages as other spamsolutions are. You need more than 1 person or team working with this software because if one of them has an issue then your server is down.
We have been using it since almost 8 years now. If we would look back in time we would say that most likely all things were fine but over time there was always something wrong…
Pros
Easy setup
Excellent support via Email, Chat & Webform.
Very clear documentation great community!
Cons
Not really suited when dealing only within gmail environment (like Gsuite)
