Sendmail的配置文件

/etc/mail/sendmail.cf :Sendmail的主配置文件；

/etc/mail/access :中繼訪問控制；

/etc/mail/domaintable ;域名映射；

/etc/mail/local-host-names ;本地主機別名；

/etc/mail/mailertable :為特定的域指定特殊的路由規則；

/etc/mail/virtusertable :虛擬域配置

Sendmail為發送服務器

[root@localhost?~]#?yum?-y?install?sendmail?sendmail-cf?openssl-devel?dovecot?cyrus* [root@localhost?~]#?nslookup >?mail.com Server:?192.168.100.243 Address:192.168.100.243#53 Name:mail.com Address:?192.168.100.243 >?192.168.100.243 Server:?192.168.100.243 Address:192.168.100.243#53 243.100.168.192.in-addr.arpaname?=?com. 243.100.168.192.in-addr.arpaname?=?mail.com. 243.100.168.192.in-addr.arpaname?=?aa.com. >?exit [root@localhost?~]#

或者

限制郵件的大小：

配置DOVECOT：

[root@localhost?~]#?sed?-i?'/protocols/s/^#//g'?/etc/dovecot/dovecot.conf

如果不做下面的操作，會報：-ERR Plaintext authentication disallowed on non-secure (SSL/TLS) connections錯誤

如果報-ERR [IN-USE] Couldn't open INBOX: Internal error occurred. Refer to server log for more information. 錯誤則

[yfshare@aa?~]$?mkdir?-p?/home/yfshare/mail/.imap/INBOX即可

在這里添加上即可（執行上面腳本也可）：

注：如果用IMAP來接收郵件，在郵件帳號里面直接寫用戶名，不加@mail.com

上面搭建的郵件服務器是使用明文傳輸的，不安全。

下面給郵件服務器弄個SSL：（dovecot默認就支持pop3s和imaps）

pop3	110	pop3s	995
smtp	25	smtps	465
imap	143	imaps	993

生成sendmail.pem文件?

[root@localhost?~]#?cd?/etc/pki/tls/certs/ [root@localhost?certs]#?make?sendmail.pem

測試成功：a/b/c三個用戶，group包含a/b用戶，c給a發送郵件并抄送給group，這時a只會收到一封郵件，Sendmail會過濾掉相同mailID的郵件。而Postfix則會給a發送兩封一模一樣的郵件

[root@localhost?~]#?mailstats Statistics?from?Thu?Sep?10?14:05:06?2015M???msgsfr??bytes_from???msgsto????bytes_to??msgsrej?msgsdis?msgsqur??Mailer4????????4?????????12K????????0??????????0K????????0???????0???????0??esmtp9???????10?????????27K???????16?????????40K????????3???????0???????0??local =====================================================================T???????14?????????39K???????16?????????40K????????3???????0???????0C???????16????????????????????0????????????????????3 [root@localhost?~]#

如果把這行注釋掉，Sendmail就不支持smtp發送郵件了，只支持smtps發送郵件

訪問：http://192.168.100.243/?admin進入后臺管理

不允許用戶添加其他的賬戶

添加個性化標題：

訪問：http://192.168.100.243進入web mail

如果出現無法載入郵件，把下面這個改成off，保存配置后再登錄即可

[root@localhost?~]#?grep?autocreate_system_folders?/var/www/html/data/_data_/_default_/configs/application.ini autocreate_system_folders?=?On [root@localhost?~]#
