Question

我正在更改主机，我需要将旧服务器上的maildir帐户转换为新服务器上的mbox。

有关最佳方法的任何想法吗？

我发现了这个：

for i in new / * cur / *; do formail＆lt;“$ i”＆gt;＆gt; ../ MBOX;完成

但我真的不明白。我有linux的基本知识，我可以通过ssh root访问我的服务器。

大部分Maildir文件夹都包含以下内容：

CUR
新
TMP
dovecot.index.log
dovecot的-uidlist
dovecot.index
dovecot.index.log.2
dovecot.index.cache
达夫科特的关键字
订阅

我是否需要所有这些或者我可以忽略dovecot文件？

非常感谢任何建议。

如果需要将maildir帐户转换为邮箱帐户而不设置邮件服务器，可以使用python的邮箱库。如果有一个maildir文件夹要转换，可以使用这个小的（10行+注释）python脚本找到here。如果有子文件夹，则需要探索子文件夹结构，这两种格式不同。这给出了以下脚本：

#!/usr/bin/env python 
# -*- coding: utf-8 -*-

Uses Python's included mailbox library to convert mail archives from
maildir [http://en.wikipedia.org/wiki/Maildir] to 
mbox [http://en.wikipedia.org/wiki/Mbox] format, icluding subfolder.

See http://docs.python.org/library/mailbox.html#mailbox.Mailbox for 
full documentation on this library.

---

To run, save as md2mb.py and run:

$ python md2mb.py [maildir_path] [mbox_filename]

[maildir_path] should be the the path to the actual maildir (containing new, 
cur, tmp, and the subfolders, which are hidden directories with names like 
.subfolde.subsubfolder.subsubsbfolder);

[mbox_filename] will be newly created, as well as a [mbox_filename].sbd the 
directory.

如果您可以通过imap访问这两个服务器（或者可以临时安排它），您可能需要考虑使用imapsync工具，例如：

http://freshmeat.net/projects/imapsync/

如果这不起作用，你应该能够忽略dovecot文件，但要注意你可能会丢失信息，比如读取哪些消息以及消息上设置的任何标志。（imapsync方法会保留所有这些东西。）
