How to Install and Use Imapsync on CentOS & Fedora

Imapsync is an IMAP transfer tool used for shifting mail boxes and e-mails from one IMAP server to another IMAP server.

Imapsync program is a comman line tool that allows step-by-step and recursive IMAP exchanges from one mail box to another, both anywhere on the internet or in your LAN.

Step 1 – Install Imapsync

Imapsync package is available under EPEL package repository. First make sure you have added EPEL on your system, if not install it first.

yum install epel-release

Once done, install imapsync package using following command.

yum install imapsync

At this level, your system is ready to migrate all data from one email account to other email accounts using IMAP.

Step 2 – Transfer Emails with IMAP

Before migration make sure both accounts have IMAP running and accessible from your system. After that use following command:

imapsync --host1 \
--user1 \
--password1 S0urcePassw0rd \
--ssl1 \
--host2 \
--user2 \
--password2 Dest1nat10NPassw0rd \

The command can take some time depends upon the size of your source Mailbox. After completing all process, you will see a long list of output. Read the output carefully to see if any error occurred during transfer. If command goes well , you will gte the result as below:
