imapsync bulk copy not copying first account in list

Ran into an issue where it looked like imapsync would fail to connect to the server on the first line when trying to do a bulk move.

mail.maildomain.com;user1@incredigeek.com;password1;mail.incredigeek.com;user2@incredigeek.com;password2

Was able to work around the issue by Adding a comment line to the top of the file. May have to do with how the script I was using handles the lines.

### Email Import list mail.maildomain.com;user1@incredigeek.com;password1;mail.incredigeek.com;user2@incredigeek.com;password2

Data is supposed to be in file.txt in the following format:

#Separator is character semi-colon ";" it can be changed by any character changing IFS=';' in the while loop below.
# Each line contains 6 columns, columns are parameter values for

and a trailing empty fake column to avoid CR LF part going
in the 6th parameter password2. Don't forget the last semicolon.
# You can add extra options after the variable "$@" Use character backslash \ at the end of each supplementary line, xcept for the last one. You can also pass extra options via the parameters of this script since they will be in "$@" The credentials filename "file.txt" used for the loop can be renamed by changing "file.txt" below. echo Looping on account credentials found in file.txt

imapsync – NO [OVERQUOTA] Not enough disk quota

msg INBOX/4624 {75129} couldn't append  (Subject:[Email message]) to folder INBOX: Error sending '55 APPEND INBOX (\Seen) "25-Aug-2017 09:12:05 -0600" {75129}': 55 NO [OVERQUOTA] Not enough disk quota (0.001 + 0.000 secs).

To resolve the above problem, check the following

  1. Email mailbox allocated size
  2. cPanel account user Quota

The above problem was due to the fact that the cPanel User Quota was maxed out. Increasing the space allocated to the account resolved the problem.

Moving emails to new host with imapsync

More info about imapsync here

Install imapsync

CentOS 7, Works on cPanel servers too

yum install epel-release && yum install imapsync

Once installed check and make sure it works.

imapsync --version

If it gives you the version number you should be good to go.

Move email account

imapsync --host1 mail.emaildomain.com --user1 username@emaildomain.com --password1  "password1" --host2 mail.exampledomain.com --user2 username@movetodomain.com --password2  "password2"

Example :

imapsync --host1 mail.myemail.com --user1 bob@myemail.com --password1  "password1" --host2 mail.incredigeek.com --user2 bob@incredigeek.com --password2  "password2"

Moving Multiple accounts

Best way to move multiple accounts is to use a script and and a list that contains all the usernames and passwords to the accounts you want to move.

example scripts can be found on the imapsync website here is a script example and here is the example file.txt

Example script.

#!/bin/sh
#
# $Id: sync_loop_unix.sh,v 1.6 2015/11/04 18:23:04 gilles Exp gilles $

# Example for imapsync massive migration on Unix systems.
# See also http://imapsync.lamiral.info/FAQ.d/FAQ.Massive.txt

# Data is supposed to be in file.txt in the following format:
# host001_1;user001_1;password001_1;host001_2;user001_2;password001_2;
# ...
# Separator is character semi-colon ";" it can be changed by any character changing IFS=';' 
# in the while loop below.
# # Each line contains 6 columns, columns are parameter values for 
# --host1 --user1 --password1 --host2 --user2 --password2
# and a trailing empty fake column to avaid CR LF part going

#
# You can add extra options after the variable "$@" 
# Use character backslash \ at the end of each suplementary line, except for the last one.
# You can also pass extra options via the parameters of this script since
# they will be in "$@"

# The credentials filename "file.txt" used for the loop can be renamed 
# by changing "file.txt" below.


echo Looping on account credentials found in file.txt
echo

{ while IFS=';' read  h1 u1 p1 h2 u2 p2 fake
    do 
        { echo "$h1" | egrep "^#" ; } > /dev/null && continue # this skip commented lines in file.txt
        echo "==== Starting imapsync from host1 $h1 user1 $u1 to host2 $h2 user2 $u2 ===="
        imapsync --host1 "$h1" --user1 "$u1" --password1 "$p1" \
                 --host2 "$h2" --user2 "$u2" --password2 "$p2" \
                 "$@"  
        echo "==== Ended imapsync from host1 $h1 user1 $u1 to host2 $h2 user2 $u2 ===="
        echo
    done 
} < file.txt

Example list of accounts to

mail.maildomain.com;user1@incredigeek.com;password1;mail.incredigeek.com;user2@incredigeek.com;password2;

 

How to use,

You can run these command from a Linux computer

Download script

wget www.incredigeek.com/home/downloads/imapsync/imapsync_loop.sh

Make the script executable

chmod +x imapsync_loop.sh

Create a text file named “imapsync_list.txt”

This file will contain the mail server to transfer from, username, and password, and then the mail server to transfer to, username and password.  Add one line per account.

Example:

mail.servertotransferfrom.com;Username1;Password1;mail.servertomoveto.com;Username2;Password2;
mail.servertotransferfrom.com;testuser;123456;mail.servertomoveto.com;bob;123456;

Execute the script to start moving mail

./imapsync_loop.sh

Troubleshooting

In the username you may need to use the username@domainname.tld, so if the username is bob, and the mail domain is incredigeek.com, use bob@incredigeek.com for the username in the imapsync_list.txt.
