Okay, now #Proton is out. @Tutanota is in. Transition was smooth & easy. Getting DNS transferred over for my custom domains was a breeze. Imports all worked. Apps seem decent. White label worked as advertised. So far so good.
@tomasino @Tutanota How did you import Tuta from proton? (mail)
@josema_ @Tutanota i used the proton mail exporter. it created an mbox directory, i believe. on the tuta side the importer worked by going to that folder and selecting all the messages. it took a few minutes to process everything.
@tomasino @Tutanota Ok. But this way the organization by folders or labels is lost. At least it can be done.
