Then, I send everything with a score of 5 or more to spam.

Their email, calendar and contacts solutions work well with iOS and android (using the DAVx app).

WebApps work flawlessly on Firefox. They have all sorts of customisation for spam filtering, catch all email addresses, etc.

But it's unclear if earlier versions are also vulnerable.

And if it did nasty things to your machine, how do you make sure that the backups you have do not include ways for the backdoor to reinstate itself?

Yes, right. People pay for negative reviews all the time. The article can still have merit. But that disclaimer is manipulative. Better just say "Tigris paid me for this content" and nothing else. Also, a "small amount" can be anything, it's all relative to what the author thinks is small.
