随着网络的发展和普及，邮件服务器正在成为人们日常生活中不可缺少的部分。现在，许多企业采用 Lotus Note, Exchange 作为公司内部的邮件服务器。本文主要介绍一种基于系统的邮件服务器软件（）提供邮件服务。

注意：之前已经配置好了LNMP web环境。

配置过程/步骤：

1. 安装Sendmail

安装或者包安装:

yum -y install sendmail sendmail-devel sendmail-cf sendmail-do m4

2. 设置在系统3和5级别启动

--level 35 sendmail on

chkconfig --list sendmail

sendmail 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭

3. 添加邮件服务器的邮件服务域名

vim /etc//local--names

将：“linux.com”添加到 local-host-names 文件中

4. 开启sendmail服务器的网络接口

sendmail.mc sendmail.mc.bak 为了防止出错，备份配置文件

vim /etc/mail/sendmail.mc

查找：DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

修改为：DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0, Name=MTA')dnl

5. 设置SMTP的用户认证

vim /etc/mail/sendmail.mc

查找：

dnl 52 TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5  PLAIN')dnldnl 53 define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl

去掉前面注释：“dnl”

在sendmail服务器中使用了saslauthd服务程序提供用户认证功能，所以要开启它

chkconfig --level 35 saslauthd on

saslauthd start

6. 生成sendmail.cf文件

/etc/mail

m4 sendmail.mc > sendmail.cf

service sendmail restart

7. 用户管理

mailuser　　　/* 建立邮件用户组*/

-g mailuser -s /sbin/ mike　　　/*建立不能登录系统的邮件用户*/

vim /etc/aliases　　　/*sendmail使用aliases机制实现邮件别名和群发功能*/

admin: mike　　　/*admin是mike的别名*/

testgroup: mike,john,tom,jack　　　/*邮件群发，向testgroup邮箱发送就是向4个人发送*/

newaliases　　　/*对aliases.db数据库更新*/

8. 安装POP3,IMAP功能

yum install dovecot

vim /etc/dovecot.conf

查找：protocols = imap imaps

修改为：protocols = imap imaps pop3 pop3s

chkconfig --level 35 dovecot on

service dovecot restart

到这里sendmail已经配置完成，开启服务器后，可以用outlook邮件客户端软件进行收发邮件。下面在介绍openwebmail的安装：

9. 安装openwebmail

下载所需软件包：www.openwebmail.org www.rpmfind.net

yum install -CGI-SpeedyCGI perl-suidperl perl--Zlib perl-Text-Iconv

rpm –ivh --nodeps openwebmail-data-2.53-3.i386.rpm

rpm –ivh --nodeps openwebmail-2.53-3.i386.rpm

10. 初始化openwebmail系统

/var/www/cgi-bin/openwebmail/openwebmail-tool.pl --

11. 修改配置文件

vim /var/www/cgi-bin/openwebmail/etc/openwebmail.conf

domainnames linux.com

default_language zh_CN.GB2312

default_iconset Cool3D.Chinese.Simplified

12. 安装Perl的FastCGI模块

下载FCGI: http://cpan.wenzk.com/authors/id/F/FL/FLORA/FCGI-0.71..gz

tar zxvf FCGI-0.71.tar.gz

cd FCGI-0.71

perl Makefile.PL

&& make install

rpm -ivh perl-FCGI-ProcManager-0.18-1.el4.rf.noarch.rpm

或者：yum install perl-FCGI-ProcManager

13. 配置Perl的FastCGI脚本（perl-fast）

vim /etc/init.d/perl-fast

#!/usr/bin/perl -use FCGI;use Socket;use FCGI::ProcManager;sub  { FCGI::CloseSocket($socket); ; }sub restart { FCGI::CloseSocket($socket); &main; }use sigtrap 'handler', \&shutdown, 'normal-signals';use sigtrap 'handler', \&restart, 'HUP';require 'syscall.ph';use POSIX qw(setsid);# FCGI_SOCKET_PATH="/tmp/perl-fastcgi.sock"#export FCGI_NPROCESSES=4#&daemonize; we don't daemonize when running under runsv#this keeps the program alive or something after 'ing perl scriptsEND() { }BEGIN() { }{no warnings;*CORE::GLOBAL::exit = sub { die "fakeexit\nrc=" . shift() . "\n"; };};eval q{exit};if ($@) {exit unless $@ =~ /^fakeexit/;}&main;sub daemonize() {chdir '/' or die "Can't chdir to /: $!";defined( my $pid = fork ) or die "Can't fork: $!";exit if $pid;setsid() or die "Can't start a new session: $!"; 0; } sub main { #.... sockets #$socket = FCGI::OpenSocket( "127.0.0.1:8999", 10 ); #.... UNIX sockets #$socket = FCGI::OpenSocket( "/temp/perl-fastcgi.sock", 10 ); #foreach $item (keys %) { delete $ENV{$item}; } #..fastcgi........ my $n_processes = $ENV{FCGI_NPROCESSES} || 4; $proc_manager = FCGI::ProcManager->new( {n_processes => $n_processes} ); #..unix socket $socket = FCGI::OpenSocket( "$ENV{FCGI_SOCKET_PATH}", 10 ); #..Socket.. 0777, $ENV{FCGI_SOCKET_PATH}; ; #use UNIX sockets - user running this script must have w access to the '' folder!! $request = FCGI::Request( \*STDIN, \*STDOUT, \*STDERR, \%req_params, $socket, &FCGI::FAIL_ACCEPT_ON_INTR ); $proc_manager->pm_manage(); if ($request) { request_loop() } FCGI::CloseSocket($socket); } sub request_loop { while ( $request->() >= 0 ) { $proc_manager->pm_pre_dispatch(); #processing any STDIN input from WebServer (for CGI-POST actions) $stdin_passthrough = ''; { no warnings; $req_len = 0 + $req_params{'CONTENT_LENGTH'}; }; if ( ( $req_params{'REQUEST_METHOD'} eq 'POST' ) && ( $req_len != 0 ) ) { my $bytes_read = 0; while ( $bytes_read < $req_len ) { my $data = ''; my $bytes = ( STDIN, $data, ( $req_len - $bytes_read ) ); if ( $bytes == 0 || !defined($bytes) ); $stdin_passthrough .= $data; $bytes_read += $bytes; } } #running the cgi app if ( ( -x $req_params{SCRIPT_FILENAME} ) && #can I execute this? ( -s $req_params{SCRIPT_FILENAME} ) && #Is this empty? ( -r $req_params{SCRIPT_FILENAME} ) #can I read this file? ) { pipe( CHILD_RD, PARENT_WR ); pipe( PARENT_ERR, CHILD_ERR ); my $pid = open( CHILD_O, "-|" ); unless ( defined($pid) ) { print("Content-: text/plain\r\n\r\n"); print "Error: CGI app returned no output - Executing $req_params{SCRIPT_FILENAME} failed !\n"; next; } $oldfh = select(PARENT_ERR); $| = 1; select(CHILD_O); $| = 1; select($oldfh); if ( $pid > 0 ) { close(CHILD_RD); close(CHILD_ERR); print PARENT_WR $stdin_passthrough; close(PARENT_WR); $rin = $rout = $ein = $eout = ''; vec( $rin, fileno(CHILD_O), 1 ) = 1; vec( $rin, fileno(PARENT_ERR), 1 ) = 1; $ein = $rin; $nfound = 0; while ( $nfound = select( $rout = $rin, undef, $ein = $eout, 10 ) ) { die "$!" unless $nfound != -1; $r1 = vec( $rout, fileno(PARENT_ERR), 1 ) == 1; $r2 = vec( $rout, fileno(CHILD_O), 1 ) == 1; $e1 = vec( $eout, fileno(PARENT_ERR), 1 ) == 1; $e2 = vec( $eout, fileno(CHILD_O), 1 ) == 1; if ($r1) { while ( $bytes = read( PARENT_ERR, $errbytes, 4096 ) ) { print STDERR $errbytes; } if ($!) { $err = $!; die $!; vec( $rin, fileno(PARENT_ERR), 1 ) = 0 unless ( $err == EINTR or $err == EAGAIN ); } } if ($r2) { while ( $bytes = read( CHILD_O, $s, 4096 ) ) { print $s; } if ( !defined($bytes) ) { $err = $!; die $!; vec( $rin, fileno(CHILD_O), 1 ) = 0 unless ( $err == EINTR or $err == EAGAIN ); } } last if ( $e1 || $e2 ); } close CHILD_RD; close PARENT_ERR; waitpid( $pid, 0 ); } else { foreach $key ( keys %req_params ) { $ENV{$key} = $req_params{$key}; } # cd to the script's local directory if ( $req_params{SCRIPT_FILENAME} =~ /^(.*)\/[^\/]+$/ ) { chdir $1; } close(PARENT_WR); #close(PARENT_ERR); close(STDIN); close(STDERR); #fcntl(CHILD_RD, F_DUPFD, 0); syscall( &SYS_dup2, fileno(CHILD_RD), 0 ); syscall( &SYS_dup2, fileno(CHILD_ERR), 2 ); #open(STDIN, "<&CHILD_RD"); exec( $req_params{SCRIPT_FILENAME} ); die("exec failed"); } } else { print("Content-type: text/plain\r\n\r\n"); print "Error: No such CGI app - $req_params{SCRIPT_FILENAME} may not exist or is not executable by this process.\n"; } } }

chmod +x /etc/init.d/perl-fast

vim /etc/profile

添加以下内容：

export FCGI_SOCKET_PATH="/tmp/perl-fastcgi.sock"export FCGI_NPROCESSES=4

执行perl-fast脚本，在后台运行。

source /etc/profile

/etc/init.d/perl-fast &

14. 配置enable_perl.conf文件，文件放在 nginx/conf 目录下。内容如下：

# openwebmailfastcgi_pass unix:/tmp/perl-fastcgi.sock;fastcgi_index openwebmail.pl;fastcgi_param GATEWAY_INTERFACE CGI/1.1;fastcgi_param SERVER_SOFTWARE nginx;fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;fastcgi_param QUERY_STRING $query_string;fastcgi_param REQUEST_METHOD $request_method;fastcgi_param CONTENT_TYPE $content_type;fastcgi_param CONTENT_LENGTH $content_length;fastcgi_param SCRIPT_NAME $fastcgi_script_name;fastcgi_param REQUEST_URI $request_uri;fastcgi_param DOCUMENT_URI $document_uri;fastcgi_param DOCUMENT_ROOT $document_root;fastcgi_param SERVER_PROTOCOL $server_protocol;fastcgi_param REMOTE_ADDR $remote_addr;fastcgi_param REMOTE_PORT $remote_port;fastcgi_param SERVER_ADDR $server_addr;fastcgi_param SERVER_PORT $server_port;fastcgi_param SERVER_NAME $server_name;fastcgi_read_timeout 60;

然后为Nginx添加FastCGI的Perl支持

server {       listen 80;       server_name mail.linuxde.net;       charset gb2312;       access_log /wslogs/linuxde/mail_access.log combined;       location / {                root /var/www;                index index.html index.htm index.;       }       location ~* .*\.pl$ {                root /var/www;                include enable_perl.conf;        }}

15. 在web服务器中发布openwebmail

为了浏览器中不用输入很长的地址，做一个引导页

vim /var/www/index.

location.href="cgi-bin/openwebmail/openwebmail.pl";

</script>

16. 文件权限的设置

# root.root /var/www/cgi-bin/openwebmail/

#chown root.mail /var/www/cgi-bin/openwebmail/*

#chmod 775 /var/www/cgi-bin/openwebmail/openwebmail*.pl

#chown root.mail /var/www/cgi-bin/openwebmail/openwebmail*.pl

#chmod 4555 /usr/bin/suidperl

#chmod 775 /var/www/cgi-bin/openwebmail/etc/sessions
