Just noticed this myself and was pleasantly surprised! Always nice to get more space without paying anything additional (looking at you fastmail…)
Is this service any good?
Works well for my purposes - can pay anonymously, your mailbox can be encrypted and servers are outside of the US. Works great with Thunderbird as well!
I’ve been using Posteo for years, and can confirm it works fine.
They are the only ones I know that provide CardDAV and CalDAVwith encryption. So you can use any or your favorite calendar app for your sync on any device.
So yes, they provide good value.
Why isn’t this recommended by PG?
