# Data is supposed to be in file.txt in the following format
#user001_1;password001_1;user001_2;password001_2
#...
# Separator is character semi-colon ; it can be changed by any character changing IFS=';'
# Each data line contains 4 columns, columns are parameters for --user1 --password1 --user2 --password2
#
# Replace "imap.side1.org" and "imap.side2.org" with your own hostname values

# This loop will also create a log file called LOG/log_${u2}_$NOW.txt for each account transfer
# where u2 is just a variable containing the user2 account name, and NOW is the current date_time
