升级到 Ubuntu 11.10 后，如何访问旧的 KMail 电子邮件？

我最初安装了 Ubuntu 11.04，并使用 KMail 收发电子邮件。一切都很好。

然后我升级到了 Ubuntu 11.10。大概 KMail 也升级了。现在 KMail 根本就无法运行；我尝试的时候，它提示“无法获取资源集合”然后崩溃了。

我不介意切换到其他电子邮件客户端，但我非常希望能够恢复我存储在 KMail 中的所有电子邮件。关于如何做到这一点，有什么建议吗？

感谢任何人提供的帮助。

使用此 shell 脚本将 mdir 转换为 mbox 格式

#! /bin/sh
#
# Get a directory name as input and convert all mail files inside
# to mbox format
#
# NOTE: processing of subdirectories not yet implemented correctly:
#       all mails in subfolders are put into the same mbox
#       (it would be better if an mbox file will be generated for
#       each subfolder)
#
# History:
# Feb 06 2001 Joerg Reinhardt
# - first edition
# Feb 07 2001 Joerg Reinhardt
# - added usage output
# Feb 12 2001 Joerg Reinhardt
# - mails not containing a 'From:' field but an 'X-From-Line:' or a
#   'Reply-To:' field are now recognised and also processed (e.g. put into
#   the mbox file); this works fine for all my mails
# - added progress information
# - warning about corrupt files is now written to stderr
# Sep 8 2012 Kim Johansson
# - Time conversion to local timezone added
# - changed grep "Date:" to grep "Date: "

# check for argument or help argument respectively
if [[ ($1 == "") ||
($1 == "-h") ||
($1 == "--help") ||
($1 == "-help") ]]; then

if [[ -d $1 ]]; then
# set target filename
dirname=`echo $1 | awk '{while(substr($0,length($0),1)=="/"){$0=substr($0,1,length($0)-1);}print $0;}'`;
mboxfile=$dirname'.mbox';

# check if directory is empty
if [[ `find $dirname -type f` == "" ]]; then
        echo $dirname": directory empty."
        exit 1;
fi;

# prevent automatic overwriting of target
if [[ -e $mboxfile ]]; then \
        dialogtext="Write file "$mboxfile"?";
        if dialog --yesno "$dialogtext" 10 60; then
        clear;
        rm -vf $mboxfile;
        else
        clear; exit 1;

如果您的邮件框格式化很容易

cd ~/.kde/share/apps/kmail/mail/
cat file1 file2 file3 ...  >>/var/spool/mail/$USER

file1 file2 file3 ...，是您的 mbox 格式的邮件文件夹（不要复制任何 .index .index.ids .index.sorted 文件）

现在，您可以通过选择本地递送从任何邮件客户端获取邮件

我使用 thunderbird：
服务器类型：Unix Movemail
服务器：localhost
这是在 Slackware 中完成的，它使用 sendmail 作为 MDA，因此你的 spool 目录可能不同。
