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。
关于最好的方法有什么想法吗?
我发现了这个:
for i in new/* cur/*;do formail <”$i” >> ../mbox;done
但我不太明白。我有 Linux 的基本知识,并且可以通过 ssh 对我的服务器进行 root 访问。
大部分 Maildir 文件夹都包含以下内容:
cur
新
tmp
dovecot.index.log
dovecot-uidlist
鸽舍索引
dovecot.index.log.2
dovecot.index.cache
鸽舍关键字
订阅
我需要所有这些还是可以忽略鸽舍文件?
如有任何建议,我们将不胜感激。

如果需要将maildir账户转换为邮箱账户,且不设置邮件服务器,可以使用python的邮箱库。如果需要转换一个 maildir 文件夹,可以使用here找到的这个小(10 行+注释)Python 脚本。如果有子文件夹,则需要探索子文件夹结构,这两种格式之间是不同的。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 访问两台服务器(或者可以临时安排),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,您应该能够忽略 dovecot 文件,但请注意,您可能会丢失信息,例如读取了哪些消息以及消息上设置的任何标志。 (imapsync 方法将保留所有这些内容。)
如果您有 Maildir 文件数据并且想要将 Maildir 文件导入到 MBOX 帐户,那么您可以借助任何能够将 Maildir 文件导入到 MBOX 帐户的第三方工具的帮助。但在我看来,您应该使用此 Maildir 到 MBOX 转换器工具的免费试用版,只需简单的点击即可将单个和多个 Maildir 文件导入到 MBOX 帐户。
