如何使用imapsync在IMAP服务器之间迁移邮箱
版本1.0
作者：Falko Timme
本指南介绍如何使用imapsync在IMAP服务器之间迁移邮箱 。 imapsync是一个IMAP同步，同步，复制或迁移工具。 成功支持超过32种不同的IMAP服务器软件。 所有标志都保留，未读将保持未读，读取将保持读取，删除将保持删除。
我不会保证这将为您工作！
1初步说明
我在这里使用两个Debian或Ubuntu服务器（程序对于其他发行版应该是一样的，只有imapsync的安装会有所不同）：
-
server1.example.com（来源） -
server2.example.com（目标）
我想将server1.example.com上的邮箱sales@example.com （username： sales@example.com ，password： secret ） 迁移到server2.example.com上的邮箱sales@example.com （用户名和密码是与server1.example.com相同）。
2我们开始之前
在我们开始之前，让我们来看看这两个邮箱，看看它们的内容（你可以使用电子邮件客户端，如Outlook，Thunderbird或基于Web的电子邮件客户端，如SquirrelMail - 我在这里使用SquirrelMail）。
server1.example.com：
server2.example.com：
迁移后，server1.example.com上的两条消息应在server2.example.com上可用 。
3 imapsync安装
如果我们在server1.example.com或server2.example.com上安装imapsync，我们甚至可以将其安装在第三个无关的服务器上。
aptitude install imapsync
要了解其用法，请查看
man imapsync
和
imapsync --help
4进行迁移
我们必须告诉imapsync我们要迁移的邮件帐户的用户名和密码。 理论上，我们可以使用--password1和--password2开关的密码，但这是危险的，因为密码会出现在
ps aux
（所以任何被允许运行该命令的用户都知道密码。）
因此，最好在包含密码的两个文件（ / etc / secret1和/ etc / secret2）中创建这两个文件（在这个例子中，这是两个邮件帐户的秘密 ），对这些文件执行chmod 600 ，然后使用- -passfile1和--passfile2开关。
echo "secret" > /etc/secret1
echo "secret" > /etc/secret2
chmod 600 /etc/secret1
chmod 600 /etc/secret2
现在我们可以使用这个简单的命令进行迁移：
imapsync --host1 server1.example.com --user1 sales@example.com --passfile1 /etc/secret2 --host2 server2.example.com --user2 sales@example.com --passfile2 /etc/secret2
以下是一个示例输出：
root@server1:~# imapsync --host1 server1.example.com --user1 sales@example.com --passfile1 /etc/secret2
--host2 server2.example.com --user2 sales@example.com --passfile2 /etc/secret2

root@server1:~#
之后我们可以删除两个密码文件：
rm -f /etc/secret1
rm -f /etc/secret2
在目标服务器（ server2.example.com ）上，注销您的IMAP帐户并重新登录（一个简单的刷新可能还不够），您应该看到来自server1.example.com的消息：
server2.example.com：
