linux安装配置sendmail实现邮件发送
sendmail配置
yum -y update sendmail sendmail-cf
SendMail相关目录
1. 设定档目录：/etc/mail
2. 记录档：/var/log/maillog
3. 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/mail
mv 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 mail
FEATURE(`dnsbl', `rbl.maps.vix.com', `Rejected - see http://www.mail-abuse.org/rbl/')dnl
FEATURE(`dnsbl', `dul.maps.vix.com', `Dialup - see http://www.mail-abuse.org/dul/')dnl
FEATURE(`dnsbl', `relays.mail-abuse.org', `Open spam relay - see http://www.mail-abuse.org/rss')dnl
dnl FEATURE(`dnsbl', `relays.ordb.org', `"Email blocked using ORDB.org - see http://ordb.org"')dnl
FEATURE(`dnsbl', `blackholes.mail-abuse.org', `"Spam blocked see: http://mail-abuse.org/cgi-bin/lookup?"$&{client_addr}')dnl
FEATURE(`dnsbl', `bl.spamcop.net', `"Spam blocked see: http://spamcop.net/bl.shtml?"$&{client_addr}')dnl
dnl FEATURE(`dnsbl',`dnsbl.sorbs.net', `"554 Rejected " $&{client_addr} " found in dnsbl.sorbs.net"')dnl
dnl FEATURE(`dnsbl', `rbl.softworking.com', `"550 Mail from "$&{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 mail
FEATURE(`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 server
163.32.250.51/32 # Epass server
163.32.250.12/32 # 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 on
service milter-greylist start
完成修改sendmail.mc档后，产生正确的sendmail.cf
cd /etc/mail
make -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 RELAY
Connect:localhost RELAY
Connect:127.0.0.1 RELAY
Connect:163.18.225 RELAY
Connect:sgrsms.sg-rs.com.hk REJECT
Connect:mail.uhome.net.tw REJECT
存档后
make all
service sendmail restart
procmail广告信过滤规则
yum install procmail
vi /etc/procmailrc
MAILDIR=/var/mail
VERBOSE=off
PATH=/bin:/sbin:/usr/bin:/usr/sbin/:/usr/local/bin:/usr/local/sbin
LOGFILE=/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。

service sendmail restar
dovecot（POP、IMAP）
安装软体111cn.net
yum -y install dovecot
cp /etc/dovecot.conf /etc/dovecot.conf.bak
vi /etc/dovecot.conf
protocols = imap imaps 修改成--> protocols = pop3
ssl_disable = no 修改成--> ssl_disable = yes
重新启动
/etc/rc.d/init.d/dovecot start
chkconfig dovecot on

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
/etc/init.d/sendmail status
没有自动启动
/etc/init.d/sendmail restart
sendmail 'aaaa' xhq6632@126.com
呵呵，收到，而且正常了。
