Problem
I am using Mailspring for two accounts with zoho mail. When I try to snooze an e-mail in one of these accounts, Mailspring crashes. After restarting Mailspring, I get sync errors for the account that I tried snoozing the mail with, rendering Mailspring unusable.
The logs tell me that the error is caused by the inability to create the folder Mailspring/Snoozed:

Context
The issue is reproducible and seems to be caused by a limitation of Zoho: Via the Zoho mail web interface I am not allowed to create a folder (or any subfolder) named “Snoozed” either.
The problem could be worked around by making the name of the “Snoozed” folder configurable in Mailspring instead of hardcoding “Mailspring/Snoozed”.
Email Provider
