sendmail配置

yum -y update sendmail sendmail-cf

SendMail相关目录1. 设定档目录：/etc/mail2. 记录档：/var/log/maillog3. 己收信件之暂存目录：/var/spool/mail/4. 寄出信件之暂存目录：/var/spool/mqueue/

先备份，后修改

cd /etc/mailmv sendmail.cf sendmail.cf.bak

解除只有Server本身可以递送信件的设定

vi /etc/mail/sendmail.mc

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

加入广告信来源过滤机制

在以下两行FEATURE(`blacklist_recipients')dnl..EXPOSED_USER(`root')dnl之间加入

dnl # use DNSBL for spam mailFEATURE(`dnsbl', `rbl.maps.vix.com', `Rejected - see http://www.mail-abuse.org/rbl/')dnlFEATURE(`dnsbl', `dul.maps.vix.com', `Dialup - see http://www.mail-abuse.org/dul/')dnlFEATURE(`dnsbl', `relays.mail-abuse.org', `Open spam relay - see http://www.mail-abuse.org/rss')dnldnl FEATURE(`dnsbl', `relays.ordb.org', `"Email blocked using ORDB.org - see http://ordb.org"')dnlFEATURE(`dnsbl', `blackholes.mail-abuse.org', `"Spam blocked see: http://mail-abuse.org/cgi-bin/lookup?"$&{client_addr}')dnlFEATURE(`dnsbl', `bl.spamcop.net', `"Spam blocked see: http://spamcop.net/bl.shtml?"$&{client_addr}')dnldnl FEATURE(`dnsbl',`dnsbl.sorbs.net', `"554 Rejected " $&{client_addr} " found in dnsbl.sorbs.net"')dnldnl FEATURE(`dnsbl', `rbl.softworking.com', `"550 Mail from "$&{client_addr}" rejected based on external blacklist - See also http://www.111cn.net/"')dnl

配置防止广告

yum install milter-greylist

vi /etc/mail/sendmail.mc，在FEATURE(`dnsbl'...描述后面加入

dnl # use GREYLIST for spam mailFEATURE(`milter-greylist')dnl

避免relay范围内的机器每次都要寄两次以上才会寄出信件

vi /etc/mail/greylist.conf

# Your own network, which should not suffer greylisting

list "my network" addr { 127.0.0.1/8 163.32.244.0/24 }

# This is a list of broken MTAs that break with greylisting. Derived from # http://cvs.puremagic.com/viewcvs/greylisting/schema/whitelist_ip.txt?rev=1.16

list "broken mta" addr {

12.5.136.141/32 # Southwest Airlines (unique sender)

12.5.136.142/32 # Southwest Airlines

163.32.250.21/32 # KH mail server163.32.250.51/32 # Epass server163.32.250.12/32 # kiecc.server# 另可在底下列出安全无虞(确定不会寄广告信)的mail server IP

chkconfig --level 345 milter-greylist onservice milter-greylist start

完成修改sendmail.mc档后，产生正确的sendmail.cf

cd /etc/mailmake -C /etc/mail

避免造成MX loop back的问题，必须将这台Server的主机别称及所有主机别名登入进来

vi /etc/mail/local-host-names

设定负责转信(帮Outlook送信)的范围(RELAY)及挡掉广告信主机(DENY)

vi /etc/mail/access

Connect:localhost.localdomain RELAYConnect:localhost RELAYConnect:127.0.0.1 RELAYConnect:163.18.225 RELAYConnect:sgrsms.sg-rs.com.hk REJECTConnect:mail.uhome.net.tw REJECT

存档后

make allservice sendmail restart PRocmail广告信过滤规则 yum install procmail

vi /etc/procmailrc

MAILDIR=/var/mailVERBOSE=offPATH=/bin:/sbin:/usr/bin:/usr/sbin/:/usr/local/bin:/usr/local/sbinLOGFILE=/var/log/procmail.log# 广告信过滤机制# 原则上因考量误判的机率较高，因为部份电子期刊也是利用相关的程式来寄发的，因此特别将这些特微的信，予以转存至特定的档案，以便日后人工确认。待确认无误后，再将设定改转存至/dev/null，以便直接删除信件，以免造成硬碟空间之浪费。# 过滤伪装寄件者:0 HBw#* ^Return-Path: .*@mail.kh.edu.tw.** ^Received: from mail.kh.edu.tw .** !^Received: from mail.kh.edu.tw .*163.32.250.* !^Received: from mail.kh.edu.tw .*163.32.119.* !^Received: from mail.kh.edu.tw .*163.29.241.* !^Received: from mail.kh.edu.tw .*163.29.242.* !^Received: from mail.kh.edu.tw .*163.32.(www.111cn.net)137.* !^Received: from mail.kh.edu.tw (localhost.localdomain [127.0.0.1])* !^Received: from 163.32.250.21 .*163.32.250./home/mailfilter/spam.local# 过滤广告信发送软体(1):0 HBw* ^X-Library: (Indy.*|Dynamailer.*)/home/mailfilter/spam.library# 过滤广告信发送软体(2):0 HBw* ^X-Mailer: (Dynamailer.*|EhooPost.*|Mail Bomber.*|QuickSender.*|made from pascual|RET.*| Foxmail*)/home/mailfilter/spam.mailer

建立告信过滤的收集目录：mkdir /home/mailfilter

设定后，到目录中编译

cd /etc/mailmake allservice sendmail restar dovecot（POP、IMAP）安装软体111cn.net

yum -y install dovecotcp /etc/dovecot.conf /etc/dovecot.conf.bakvi /etc/dovecot.conf

protocols = imap imaps 修改成--> protocols = pop3ssl_disable = no 修改成--> ssl_disable = yes

重新启动

/etc/rc.d/init.d/dovecot startchkconfig dovecot on

sendmail不能正常发邮件

显然不行，肯定有问题

找原因中

没有找到，对它的配置也不熟悉，网上没有找到方法

运行yast删除了，重新安装

linux-qebs:/srv/www/htdocs # rpm -qa | grep sendmail sendmail-8.14.3-51.5.1.i586

sendmail -bd -q12h

vi /etc/sendmail.cf

修改配置

原来为

Timeout.ident=5s

修改后

Timeout.ident=0s
