Shifting your email hosts and don’t know how to migrate the emails to the new server? Here today we will guide you how easy it is to migrate emails over IMAP. This entire process is made simple by free and open source tool called imapsync. Credits to the developer Gilles LAMIRAL for creating such a great tool.

 

Imapsync is an IMAP transfers tool. The purpose of imapsync is to migrate IMAP accounts or to backup IMAP accounts. IMAP is one of the three current standard protocols to access mailboxes, the two other are POP3 and HTTP with webmails. Imapsync runs on Windows, Linux, Mac OS X. Before we start working with the tool we need to first install it on our system.
