@thunderbird
I didnt find it stated explicitly. will thundermail be hosted on US servers?

@rainyday @thunderbird no. Servers will be in the EU. Likely Germany to start. Not sure what other EU countries we will host in. Will post more on this soon.

@thunderbird I was recently wondering if this was going to be a thing at some point, glad to see it!!!

@ryanleesipes @thunderbird Great news, thank you!

@rainyday @thunderbird our goal, first and foremost, is to protect user data.

@thunderbird Will there be a web interface for ThunderMail?

It's a planned post-launch feature!

@thunderbird really wish you would come out with an iOS version of thunderbird.

@saintfrancis We've just hired our iOS developer, and the repository will be going public soon. So it's in the works!

@ryanleesipes @rainyday @thunderbird

Do you know of any plans to make it HIPAA compliant?

@thunderbird with a feature like calendar being part of the suite will calendar be coming to Thunderbird on Android?

@paulhullford Thanks for asking! These are two separate products, and right now, there's no timeline for a built-in calendar on the Android app. But a good way to show support is upvoting suggestions like this on Mozilla Connect: https://connect.mozilla.org/t5/ideas/calendar-support-on-thunderbird-mobile/idi-p/76394
