====== 將 Mail Server - IMAP 建立的中文目錄編碼轉回作法  ======

透過 [[https://imapsync.lamiral.info/|imapsync]] 移轉 Mail Server 過程, 發現一些使用中文所建立的目錄無法成功移轉, 又不好比對出是那些目錄, 所以找了一下可以如何將編碼轉回的方式.

  * 在 imapsync 執行後的 LOG_imapsync 目錄內看到記錄檔最後有出現 Err Exp.<file>

===== CentOS 6 安裝 perl Unicode::IMAPUtf7 套件 =====
  * <code sh>
yum install https://www.rpmfind.net/linux/dag/redhat/el6/en/x86_64/dag/RPMS/perl-Unicode-IMAPUtf7-2.00-1.el6.rf.noarch.rpm
</code>

===== 簡單寫個轉碼 perl 程式 =====
  * <code perl test.pl>
#!/usr/bin/perl
use Unicode::IMAPUtf7;

my $IMAPUtf7 = Unicode::IMAPUtf7->new();

$encode = '[from ABC/&ZbBbomI2--DATA/INDIA/JonathanTest.] [from ABC/&ZbBbomI2--DATA/Vietnam/TrysoftTest]';
$decode = $IMAPUtf7->decode($encode);
print("[$decode]\n");
</code><cli>
root@ct-centos6 ~]# perl test.pl
[[from ABC/新客戶-DATA/INDIA/JonathanTest.] [from ABC/新客戶-DATA/Vietnam/TrysoftTest]]
[root@ct-centos6 ~]#
</cli>
