# Channel - connects two stores defining their synchronization
# Account - connection details for network stores
# Group - a set of channels

## ABOUT THIS FILE:
## Many .mbsyncrc example files exist, most showing how to migrate
## from Gmail to local mail.  This one is different.  In here we
## move a Gmail account to an existing IMAP account on another
## system (Privateemail, a NameCheap service - not an ad, but I am
## satisfied with the ease, price, and reliability).  To avoid
## folder collisions, everything in here is moved to "from-gmail"
## in the destination system.  The Gmail inbox folder is move to
## the inbox of the target system.  Nothing is deleted on either
## side.   Using a free-tier Ubuntu EC2 instance in AWS I was able
## to install isync, scratch out this file and run it to have all
## 9-ish GB of mail moved over in a few hours (overnight). *****
