sendmail：如何在 ubuntu 上配置 sendmail？ [关闭]

当您输入 sudo sendmailconfig 时，系统应该会提示您配置 sendmail。

作为参考，配置期间更新的文件位于以下位置（如果您想手动更新它们）：

/etc/mail/sendmail.conf
/etc/cron.d/sendmail
/etc/mail/sendmail.mc

您可以通过在命令行中键入以下内容来测试 sendmail 以查看它是否已正确配置和设置：

$ echo "My test email being sent from sendmail" | /usr/sbin/sendmail myemail@domain.example

以下将允许您将 smtp 中继添加到 sendmail：

#Change to your mail config directory:
cd /etc/mail

#Make a auth subdirectory
mkdir auth
chmod 700 auth

#Create a file with your auth information to the smtp server
cd auth
touch client-info

#In the file, put the following, matching up to your smtp server:
AuthInfo:your.isp.net "U:root" "I:user" "P:password"

#Generate the Authentication database, make both files readable only by root
makemap hash client-info < client-info
chmod 600 client-info
cd ..

将以下行添加到 sendmail.mc，但在 MAILERDEFINITIONS 之前。确保更新您的 smtp 服务器。

define(`SMART_HOST',`your.isp.net')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
FEATURE(`authinfo',`hash -o /etc/mail/auth/client-info.db')dnl

调用创建 sendmail.cf（或者运行 make -C /etc/mail）：

m4 sendmail.mc > sendmail.cf

重新启动 sendmail 守护进程：

service sendmail restart

经过一次小的编辑后，我得到了最佳答案（尚无法回复）

这对我不起作用：

FEATURE('authinfo','hash /etc/mail/auth/client-info')dnl

每个字符串的第一个单引号应更改为反引号 (`)，如下所示：

FEATURE(`authinfo',`hash /etc/mail/auth/client-info')dnl

更改后我运行：

sudo sendmailconfig

我在做生意:)

结合上面的两个答案，我终于让它工作了。请注意，每个字符串的第一个单引号是文件 sendmail.mc 中的反引号 (`)。

#Change to your mail config directory:
cd /etc/mail

#Make a auth subdirectory
mkdir auth
chmod 700 auth  #maybe not, because I cannot apply cmd "cd auth" if I do so.

#Create a file with your auth information to the smtp server
cd auth
touch client-info

#In the file, put the following, matching up to your smtp server:
AuthInfo:your.isp.net "U:root" "I:user" "P:password"

#Generate the Authentication database, make both files readable only by root
makemap hash client-info < client-info
chmod 600 client-info
cd ..

#Add the following lines to sendmail.mc. Make sure you update your smtp server
#The first single quote for each string should be changed to a backtick (`) like this:
define(`SMART_HOST',`your.isp.net')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
FEATURE(`authinfo',`hash /etc/mail/auth/client-info')dnl

#run 
sudo sendmailconfig
