This article will show you how to transfer mail between different servers using the IMAPSync utility through a primitive user interface.
On the destination server, you must have a mailbox with the required username and password. Before using Imapsync, be sure to install it (https://imapsync.lamiral.info/#install).
Due to the organization's prohibition to use passwords from employees' mailboxes in the script, we pass the migration process to the user. For this, a web user interface has been developed, which consists of a form module (gis.html) and an imapsync script launcher (gis.php). Filling imap servers can be automated by analyzing the contents of the mailbox name field. Using Fetchmail as a roundcube plugin is out of the question. I have not found a detailed coherent analysis of this issue.
The web interface consists of fields with information about mailboxes, an area for outputting the operation and control buttons (gis.html).

The mailbox migration script (startimapsync.sh) accepts command line parameters: logins and passwords for the imap server of the source and destination mailboxes, respectively.
