Imapsync is an IMAP transfer tool used for copying emails from one IMAP server to another IMAP server. This article will help you to install imapsync on Ubuntu, Debian, and Linuxmint systems and transfer all your Mailboxes and emails between two IMAP servers.

Step 1 – Prerequisites
Let’s start with the installation of the required packages for imapsync. Here is a long list of Perl libraries and other packages to install on your system.
sudo apt-get install git rcs make makepasswd cpanminus sudo apt-get install gcc libssl-dev libauthen-ntlm-perl \ libclass-load-perl libcrypt-ssleay-perl liburi-perl \ libdata-uniqid-perl libdigest-hmac-perl libdist-checkconflicts-perl \ libfile-copy-recursive-perl libio-compress-perl libio-socket-inet6-perl \ libio-socket-ssl-perl libio-tee-perl libmail-imapclient-perl \ libmodule-scandeps-perl libnet-ssleay-perl libpar-packer-perl \ libreadonly-perl libsys-meminfo-perl libterm-readkey-perl \ libtest-fatal-perl libtest-mock-guard-perl libtest-pod-perl \ libtest-requires-perl libtest-simple-perl libunicode-string-perl
Also, install required Python modules using CPAN on your system.
sudo cpanm Crypt::OpenSSL::RSA Crypt::OpenSSL::Random --force sudo cpanm Mail::IMAPClient JSON::WebToken Test::MockObject sudo cpanm Unicode::String Data::Uniqid
Step 2 – Install Imapsync
After completing the installation of required packages. Download latest imapsync code from its official Github repository on your local system.
git clone https://github.com/imapsync/imapsync.git
Navigate to newly cloned repository and install it with the following commands on your system.
cd imapsync mkdir -p dist sudo make install
At this stage, your system is ready to migrate all data from one email account to another email accounts using IMAP.
Step 3 – Transfer Emails with IMAP
So you are ready for migration. Before migration make sure both accounts have IMAP running and accessible from your system. After that use following command syntax.
imapsync --host1 imap.source.example.com \ --user1[email protected] \ --password1S0urcePassw0rd \ --ssl1 \ --host2imap.dest.example.com \ --user2[email protected] \ --password2Dest1nat10NPassw0rd \ --ssl2
The command will take a long time as per the size of your source Mailbox. After completing all process, you will see a long list of output. Check the output to find if any error occurred during transfer. Below is the small part of the result.

Reference:
Same for me today on ubuntu 20.04, had to install the following too :
sudo cpanm Crypt::OpenSSL::RSA Encode::IMAPUTF7 File::Tail JSON::WebToken::Crypt::RSA Regexp::Common Encode::IMAPUTF7 Test::Deep
So the following lien is enough for installing all perl modules in one time :
sudo cpanm Mail::IMAPClient JSON::WebToken Test::MockObject Unicode::String Data::Uniqid Crypt::OpenSSL::RSA Encode::IMAPUTF7 File::Tail JSON::WebToken::Crypt::RSA Regexp::Common Encode::IMAPUTF7 Test::Deep
Debian 10:
apt-get install apt-file; apt-file update
cpanm Encode::IMAPUTF7 File::Tail LWP::UserAgent Regexp::Common Test::Deep
Add these before make install as well.
I had the same problem. Make sure you run everything as root (via sudo). I got stuck because Crypt::OpenSSL::RSA would not install because Crypt::OpenSSL::Random was not installed. I was finally able to install that after running:
sudo apt-get install libssl-dev
Run ‘sudo cpanm Crypt::OpenSSL::Random’ and ‘sudo cpanm Crypt::OpenSSL::RSA’ after that.
I was finally able to get successful build after that. You may encounter other issues. Running ‘make -d’ will give more info about where the build is failing. I also ran ‘sh -x INSTALL.d/prerequisites_imapsync’ to help track things down. Hope this helps.

Hi Wendy,
I hope you are doing well. I have followed all steps to install imapsync. When i enter imapsync then imapsync: command not found error is showing. Kindly help me to sort out this issue. Thanks
Th e autor should really test the guide with a clean install. the packages “ssl” and “libssl-dev” are missing
To recover:
sudo apt-get install gcc
sudo apt-get install libssl-dev
sudo cpanm Crypt::OpenSSL::Random –force
sudo cpanm Crypt::OpenSSL::RSA –force
sudo make clean
sudo make install
Thank you!
Tutorial has been updated with your suggestions.
Hy, thx for this tuto.
I try in Linux Mint 19.2.
The installation is missing various packages of cpan:
Failure: Not found Perl module File::Tail
Failure: Not found Perl module Package::Stash::XS
Failure: Not found Perl module Regexp::Common
Failure: Not found Perl module Test::Deep
to install it:
sudo cpanm File::Tail Package::Stash::XS Regexp::Common Test::Deep
and ready, to me it already works correct.
Thx.

Hello,
I hope you can still answer my question. Done everything you suggested but an error came up with installing IMAP. Here is the error I get:
~/imapsync$ sudo make install

$0 gives INSTALL.d/prerequisites_imapsync

What you have to do before using imapsync:
Install Perl module Crypt::OpenSSL::RSA
Install Perl module JSON::WebToken::Crypt::RSA
Install Perl module Regexp::Common
Here is a cpanm command to install missing Perl modules:
cpanm Crypt::OpenSSL::RSA JSON::WebToken::Crypt::RSA Regexp::Common
Makefile:99 : la recette pour la cible « testp » a échouée
make: *** [testp] Erreur 1
Some modules/librairies seem to be missing. Any advice.
Thanks.
Simon
