# Example for imapsync massive migration on Unix systems.
# 
# Data is supposed to be in imapsync.csv in the following format
# user1_001;pass1_001;user2_001;pass2_002
# user1_002;pass1_002;user2_002;pass2_003
# ...
# Separator is character semi-colon ";" 
# Each data line contains 4 columns, columns are parameters for --user1 --password1 --user2 --password2
#
# HashTag # indicates this line to be skipped.
#
# Server names are entered via cli
#
# Usage example: imapsync-many.sh <server1> <server2> <mailbox-file> <options-string>
