[Debian] Migrate E-mail using imapcopy

What is imapcopy?

IMAPCopy is a small command line tool to copy messages for multiple users from one imap server to another. It was designed for migration of Linux imap mail to exchange servers.

Installation Debian and Ubuntu

  • Install the package via SSH

apt-get install imapcopy

  • Create a configuration file you can use the example below

SourceServer mail.domainname.net

SourcePort 143

DestServer ex.myhosting.com

DestPort 143


skipfolder INBOX.Trash

skipfolder INBOX.Sent

skipfolder "INBOX.Sent Objects"

#       SourceUser                  SourcePassword   DestinationUser DestinationPassword

Copy    "colin@domainname.net"       "password"         "Tester@domainname.com"          "2dngog.0?bogcnb"

Run the import

  • Running the import is actually very simple once the configuration is setup simply type imapcopy on the directory the cfg file is located in.
  • If successful the output of the application will be as follows
