mailx官網：http://www.filewatcher.com/d/CentOS/x86_64/Applications/Internet/mailx-12.4-6.el6.x86_64.rpm.239876.html
一、rpm包下載地址：
wget ftp://ftp.iij.ad.jp/pub/linux/centos-vault/6.2/os/x86_64/Packages/mailx-12.4-6.el6.x86_64.rpm --2017-07-03 08:21:57-- ftp://ftp.iij.ad.jp/pub/linux/centos-vault/6.2/os/x86_64/Packages/mailx-12.4-6.el6.x86_64.rpm => ‘mailx-12.4-6.el6.x86_64.rpm’ Resolving ftp.iij.ad.jp (ftp.iij.ad.jp)... 202.232.140.70, 2001:240:bb8f::1:70 Connecting to ftp.iij.ad.jp (ftp.iij.ad.jp)|202.232.140.70|:21... connected.

二、安裝mailx
[root@sendmail tools]# rpm -ivh mailx-12.4-6.el6.x86_64.rpm warning: mailx-12.4-6.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID c105b9de: NOKEY Preparing... ################################# [100%] Updating / installing... 1:mailx-12.4-6.el6 ################################# [100%] [root@sendmail tools]# ll total 236 -rw-r--r-- 1 root root 239876 Jul 3 08:22 mailx-12.4-6.el6.x86_64.rpm [root@sendmail tools]# rpm -qa mailx mailx-12.4-6.el6.x86_64 [root@sendmail tools]# mailx -V 12.4 7/29/08
三、配置mailx (在配置文件結尾加入下面這段代碼)
[root@sendmail tools]# vi /etc/mail.rc #send mail set from=zhhotdoor@163.com set smtp=smtp.163.com set smtp-auth-user=zhhotdoor@163.com set smtp-auth-password=******* #換成你郵件密碼 set smtp-auth=login
四、發送郵件命令（測試用了163郵件，發送成功）
[root@sendmail tools]# echo hello word | mailx -v -s " title" zhhotdoor@163.com Resolving host smtp.163.com . . . done. Connecting to 123.125.50.135 . . . connected. 220 163.com Anti-spam GT for Coremail System (163com[20141201]) >>> EHLO sendmail.template.com 250-mail 250-PIPELINING 250-AUTH LOGIN PLAIN 250-AUTH=LOGIN PLAIN 250-coremail 1Uxr2xKj7kG0xkI17xGrU7I0s8FY2U3Uj8Cz28x1UUUUU7Ic2I0Y2UF3mSHyUCa0xDrUUUUj 250-STARTTLS 250 8BITMIME >>> AUTH LOGIN 334 dXNlcm5hbWU6 >>> emhob3Rkb29yQDE2My5jb20= 334 UGFzc3dvcmQ6 >>> aG90ZG9vcjEyMw== 235 Authentication successful >>> MAIL FROM:<zhhotdoor@163.com> 250 Mail OK >>> RCPT TO:<zhhotdoor@163.com> 250 Mail OK >>> DATA 354 End data with <CR><LF>.<CR><LF> >>> . 250 Mail OK queued as smtp5,D9GowADngWRuE1lZypxwAw--.24084S2 1499009903 >>> QUIT 221 Bye
五、查看郵件是否收到
六、錯誤問題
測試發現有時能發送，有時會退信並報以下錯誤：
>>> . 554 DT:SPM 163 smtp3,DdGowACnhqntEllZcKFeAw--.22918S2 1499009775,please see http://mail.163.com/help/help_spam_16.htm?ip=27.42.98.89&hostid=smtp3&time=1499009775 smtp-server: 554 DT:SPM 163 smtp3,DdGowACnhqntEllZcKFeAw--.22918S2 1499009775,please see http://mail.163.com/help/help_spam_16.htm?ip=27.42.98.89&hostid=smtp3&time=1499009775 "/root/dead.letter" 0/0 . . . message not sent.
554 DT:SPM 發送的郵件內容包含了未被許可的信息，或被系統識別為垃圾郵件。請檢查是否有用戶發送病毒或者垃圾郵件
查了下原因，因為163反垃圾郵件設置的原因，所有我采用了qq郵箱及hostmail
qq郵箱
|
1
2
3

5
|
set
from=224******53@qq.com
set
smtp=smtp.qq.com
set
smtp-auth-user=224******53@qq.com
set
smtp-auth-password=euia********chb
#授權碼
set
smtp-auth=login
|
錯誤提示：
530 Error: A secure connection is requiered(such as ssl). More information at http://service.mail.qq.com/cgi-bin/help?id=28
smtp-server: 530 Error: A secure connection is requiered(such as ssl). More information at http://service.mail.qq.com/cgi-bin/help?id=28
"/root/dead.letter" 19/438
. . . message not sent
於是我改了下配置文件添加了幾個參數
|
1
2
3
4
5
6
7
8
|
set
from=224******53@qq.com
set
smtp=smtp.qq.com
set
smtp-auth-user=224******53@qq.com
set
smtp-auth-password=euia********chb
set
smtp-auth=login
set
smtp-use-starttls
set
ssl-verify=ignore
set
nss-config-
dir
=
/etc/pki/nssdb/
|
郵件發送成功，在/etc/pki/nssdb/有證書文件
當然還有兩個方式可以獲取證書文件
|
1
2
3
4
5
|
mkdir
-p
/root/
.certs/
echo
-n | openssl s_client -connect smtp.qq.com:465 |
sed
-
ne
'/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'
> ~/.certs
/qq
.crt
certutil -A -n
"GeoTrust SSL CA"
-t
"C,,"
-d ~/.certs -i ~/.certs
/qq
.crt
certutil -A -n
"GeoTrust Global CA"
-t
"C,,"
-d ~/.certs -i ~/.certs
/qq
.crt
certutil -L -d
/root/
.certs
|
然后mail.rc的配置文件改成
|
1
2
3
4
5
6
7
8
|
set
from=224******53@qq.com
set
smtp=smtp.qq.com
set
smtp-auth-user=224******53@qq.com
set
smtp-auth-password=euia********chb
set
smtp-auth=login
set
smtp-use-starttls
set
ssl-verify=ignore
set
nss-config-
dir
=
/root/
.certs
|
有些郵箱無法通過上述方式獲取證書，我們可以在裝有火狐瀏覽器的服務器中把證書拷貝過來

[root@localhost

把這個三個文件拷貝到指定文件下。比如：/root/.certs1
|
1
2
3
4
5
6
7
8
|
set
from=224******53@qq.com
set
smtp=smtp.qq.com
set
smtp-auth-user=224******53@qq.com
set
smtp-auth-password=euia********chb
set
smtp-auth=login
set
smtp-use-starttls
set
ssl-verify=ignore
set
nss-config-
dir
=
/root/
.certs1
|
mailx的操作還是蠻簡單的，就是一直報一個錯誤
Error in certificate: Peer's certificate issuer is not recognized.
證書沒有獲得認可
解決方法：找個存放證書的目錄

這樣就不會報錯了。

七、sendEmail（目前還沒有測試）
下面來介紹sendEmail的使用
|

|
wget http:
//caspian
.dotconf.net
/menu/Software/SendEmail/sendEmail-v1
.56.
tar
.gz
tar
-zxvf sendEmail-v1.56.
tar
.gz
cd
sendEmail-v1.56
mv
sendEmail
/usr/local/bin/
yum -y
install
perl-IO-Socket-SSL openssl-perl openssl-devel
|
sendEmail就可以使用了。應為sendEmail沒有配置文件，所以在發送郵件的時候需要填上發件人的賬戶密碼，沒有mailx方便.
這是我們需要腳本輔助

#!/bash/sh
from_email=
'username@hotmail.com'
smtp=
'smtp-mail.outlook.com:587'
title=
'標題'
to_email=`username@qq.com`
passwd
=
'passwd'
body=`
cat
test
`
/usr/sbin/sendEmail

-f

-o message-content-

"$to_email"
-xu

-xp
"$passwd"
-m

|
以上是個簡單的腳本，當然標題和內容以及發件人你都可以傳參進來。這樣的話就不會再命令行中暴露密碼。
