Had some horror to migrate my old Thunderbird archive to IMAP.. found this script. I have made some additions to this code:
- replace '.' (dots) by '_' in folder names
- subscribe to the folders !
- create (final) dir on other location
- appended a base target folder
use warnings;
use strict;

my $base_target = "INBOX";

my $imap_user = "username";
my $imap_pass = "password";
my $parseropts = {
enable_cache => 0,
enable_grep => 0,
cache_file_name => 'cache-file',
};
my $skip_deleted = 1;
my $imap = Mail::IMAPClient->new(
Server => $imap_server,
User => $imap_user,
Password => $imap_pass,

parse_dir($base_dir);
sub parse_dir {
my $dir = shift;
opendir my $dir_h, $dir
or die "Unable to opendir $dir: $!\n";
print "Reading directory $dir\n";
##Dirty, probably IMAP-server dependent stuff.
