Is 120 per year really ridiculous? (I assume Monat -> month). For something as crucial to online comms as email I'd be happy to pay if it was as reliable as other offerings (and ideally extensible in some form - e.g if it could do contact/calendar sync too).

I'm considering trying out https://mykolab.com at some point as it looks like it might meet my needs. That looks like it would be around $12pcm.

Isn't that how it is working? For example The cost of bandwidth is 10x less in US based datacenters, compared to Indian datacenter (despite lower wages/other costs)

300 GB transfer Vs 30 GB transfer. Who would you host your services with?

If you are concerned about your security (not that I'm validating Mailbox.org), don't always go for the cheapest options; Or as uncle Sam says

"there is always a catch junior, always!"

That is the one I was referring to. I don't think it reasonable to ask €10,- per month because that is just ridiculous compared to the costs that they are making.

Of course it is an important service. But it would also be outrageous to ask €1.000 for a bottle of water when someone is dying of thirst in the desert. That would just be a dick move. Although less extreme, mykolab is similar.

You've never been to Switzerland, have you?

The price of an extra large coffee at Starbucks per month for highly secure groupware accounts? Surely, that is obscene. </irony>

The frontpage is entirely in German, but the actual web interface is not with the exception of one settings module.

You can switch to English, French, Spanish, Italian and other languages easily.

The €1 is for the smallest package. You get 3 email aliases, 10,000 emails per day quota, 2GB of email storage, and 100 MB of Office storage.
