CentOS安裝maildrop下載生成RPM與創建maildrop rpm
經過長時間學習CentOS安裝maildrop，你可能會遇到CentOS安裝maildrop下載問題，這里將介紹CentOS安裝maildrop問題的解決方法，他的縮寫既是CentOS。CentOS社區將Redhat的網站上的所有源代碼下載下來，進行重新編譯。操作系統CentOS安裝maildrop。
A、CentOS安裝maildrop下載生成RPM
[root@localhost postfix]# cd
[root@localhost ~]# wget http://prdownloads.sourceforge.net/courier/maildrop-2.0.4.tar.bz2
[root@localhost ~]# cp maildrop-2.0.4.tar.bz2 $SOURCE
[root@localhost ~]# tar xjf maildrop-2.0.4.tar.bz2
[root@localhost ~]# cd maildrop-2.0.4
[root@localhost maildrop-2.0.4]# cp maildrop.spec $SPEC
[root@localhost maildrop-2.0.4]# cd $SPEC
CentOS安裝編輯maildrop.spec 把下面：
BuildRequires: /usr/include/fam.h gdbm-devel pcre-devel
改為：
BuildRequires: gdbm-devel pcre-devel
把下面：
%configure --with-devel --enable-userdb --enable-maildirquota \
--enable-syslog=1 --enable-trusted-users='root mail daemon postmaster qmaild mmdf' \
--enable-restrict-trusted=0 \
--enable-sendmail=/usr/sbin/sendmail
改為：
%configure --with-devel --enable-userdb --enable-maildirquota \
--enable-syslog=1 --enable-trusted-users='root mail daemon postmaster qmaild mmdf' \
--enable-restrict-trusted=0 --enable-sendmail=/usr/sbin/sendmail \
--enable-authlib
B、CentOS安裝創建maildrop rpm
[root@localhost SPECS]# yum -y install pcre-devel
[root@localhost SPECS]# rpmbuild -bb maildrop.spec
[root@localhost SPECS]# cd $RPMS/i386
[root@localhost i386]# rpm -ivh maildrop-2.0.4-1.i386.rpm
C、CentOS安裝添加虛似用戶及創建目錄
[root@localhost i386]# cd
[root@localhost ~]# groupadd -g 1000 vgroup
[root@localhost ~]# useradd -g 1000 -u 1000 -s /sbin/nologin -d /dev/null vuser
編輯/etc/postfix/master.cf ，加入下面的內容：
maildrop unix - n n - - pipe
flags=DRhu user=vuser argv=/usr/bin/maildrop -d ${user}@${nexthop} ${recipient} ${user} ${extension} ${nexthop}
D、CentOS安裝創建郵件存儲目錄
[root@localhost ~]# mkdir -p /home/data/domains/extmail.org/postmaster
[root@localhost ~]# maildirmake /home/data/domains/extmail.org/postmaster/Maildir
[root@localhost ~]# chown -R vuser:vgroup /home/data/domains/
E、CentOS安裝測試maildrop
[root@localhost ~]# echo "test" | maildrop -V 10 -d postmaster@extmail.org
maildrop: authlib: groupid=1000
maildrop: authlib: userid=1000
maildrop: authlib: logname=postmaster@extmail.org, home=/home/data/domains/extmail.org/postmaster, mail=/home/data/domains/extmail.org/postmaster/Maildir/
maildrop: Changing to /home/data/domains/extmail.org/postmaster
Message start at 0 bytes, envelope sender=postmaster@extmail.org
maildrop: Attempting .mailfilter
maildrop: Delivery complete.
出現上以信息說明authlib，maildrop 工作正常
F、CentOS安裝測試pop3
[root@localhost ~]# telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
+OK Hello there.

+OK POP3 clients that break here, they violate STD53.
1 6
.
retr 1
+OK 6 octets follow.
test
.
quit
+OK Bye-bye.

G、CentOS安裝測試postfix
[root@localhost ~]# perl -MMIME::Base64 -e 'print encode_base64("postmaster\@extmail.org");'
cG9zdG1hc3RlckBleHRtYWlsLm9yZw==
[root@localhost ~]# perl -MMIME::Base64 -e 'print encode_base64("extmail");'
ZXh0bWFpbA==
[root@localhost ~]# service postfix restart （重啟一下）
[root@localhost ~]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
