A bash script to clone multiple email-password combinations from one imap host to another. Requires imapsync installed/compiled and a csv file for email list. Uses port 993+ssl as default.

imap-sync.sh

#!/bin/sh
# CSV file line example:
# [email protected],PASSWORD

if [ -z "$1" ]
	then
		echo "CSV file is not specified!"
		exit 1
fi

if [ -z "$2" ]
	then
		echo "Missing host name (ex: imap.gmail.com or outlook.office365.com)"
		exit 1
fi

FILE=$1
HOST=$2

EMAIL=()
PASS=()

counter=0
for line in `cat $FILE`; do
{
	EMAIL[counter]=`echo "$line" | cut -d, -f1`
	PASS[counter]=`echo "$line" | cut -d, -f2`

	((counter++))
};
done;

function doOne {

	if [ "$counter" -eq "$lastitem" ]; then

	fi

	E=${EMAIL[counter]}
