熊熊亂說話

執行rpm -qa|egrep -i 'perl-5|perl-TimeDate'，確認已經安裝Perl與TimeDate兩個元件。(http://search.cpan.org/~gbarr/TimeDate-1.16/)

下載http://batleth.sapienti-sat.org/projects/mb2md/mb2md-3.20.pl.gz

解開mb2md-3.20.pl.gz

chmod ＋x mb2md-3.20.pl

mv mb2md-3.20.pl /usr/local/bin/mb2md

執行下面的Shell Scrip

#!/bin/sh

MBOXDIR="/var/spool/mail"

MAILDIR="/var/spool/maildir"

cd $MBOXDIR

for user in *; do

mkdir -p $MAILDIR/$user

mb2md -s $MBOXDIR/$user -d $MAILDIR/$user/

chmod -R 700 $MAILDIR/$user/

chown -R $user.$user $MAILDIR/$user/

done

結束後，就會將/var/spool/mail轉換到/var/spool/maildir。

修改Postfix的main.cf設定(/etc/postfix/main.cf)，加入下面這行：

mail_spool_directory=/var/spool/maildir/

修改Dovecot IMAP設定檔：(/etc/dovecot.conf)

default_mail_env=maildir:/var/spool/maildir/%u

接下來，全部發信會有問題：

said: 451 4.5.0 Error in processing, id=16056-04, mime_decode-1 FAILED: MIME::

Parser: can't open tmpfile: Invalid argument (in reply to end of DATA command))

解法很簡單，跟著下面步驟。

修改/var/spool/maildir ownner 要跟舊的 /var/spool/mail 一樣。

執行下面兩個目錄權限異動：

chmod 1777 /var/spool/maildir/

chmod 1777 /tmp

如果還有queue，在下postsuper -r ALL。
