如何让 ssmtp 将本地用户映射到 To: 字段的电子邮件地址

Question

我有一个简单的ssmtp设置。

该命令echo test | mail -s "testing" username总是导致我试图发送一封username@hostname总是失败的电子邮件。

因此，我试图将本地用户名映射到特定的电子邮件地址。

我该怎么做呢？

我试过了/etc/aliases，但是

$ sudo newaliases 
newaliases: Aliases are not used in sSMTP

然后我试过了

$ cat /etc/mail.rc 
alias root root<xxx@yyy.com>
alias username username<xxx@yyy.com>

但它仍然不起作用。有任何想法吗？

我也有点挣扎ssmtp。我学到的第一件事是别名机制不适用于普通mail程序；我必须mailx从包中使用bsd-mailx- 不知道为什么。因此，在开始更改配置之前，请先检查一下。

无论如何，作为参考，我有一个ssmtp如下所示的工作设置：

1. 文件 /etc/ssmtp/ssmtp.conf：

   #
   # Config file for sSMTP sendmail
   #
   # The person who gets all mail for userids < 1000
   # Make this empty to disable rewriting.
   root=romano@mymail.domain.com
   
   # The place where the mail goes. The actual machine name is required no 
   # MX records are consulted. Commonly mailhosts are named mail.domain.com
   mailhub=mymailserver.mymail.domain.com:25
   
   # Where will the mail seem to come from?
   rewriteDomain=mymail.domain.com
   
   # The full hostname
   hostname=myhostname.mymail.domain.com
   # Use SSL/TLS before starting negotiation 
   UseTLS=No
   #UseSTARTTLS=Yes
   #
   # Are users allowed to set their own From: address?
   # YES - Allow the user to specify their own From: address
   # NO - Use the system generated From: address
   FromLineOverride=NO
   

2. 文件 /etc/ssmtp/revaliases/

   # sSMTP aliases
   # 
   # Format:   local_account:outgoing_address:mailhub
   #
   # Example: root:your_login@your.domain:mailhub.your.domain[:port]
   # where [:port] is an optional port number that defaults to 25.
   #
   root:romano@mymail.domain.com
   romano:romano@mymail.domain.com
   postmaster:romano@mymail.domain.com
   

现在它起作用了：

[romano:~] % mailx -v root
Subject: test
test
.

[<-] 220 mymailserver.mymail.domain.com ESMTP my mail server
