如何让 ssmtp 将本地用户映射到收件人：字段的电子邮件地址

我有一个简单的ssmtp设置。

该命令echo test | mail -s "testing" username总是导致我尝试发送一封电子邮件，但username@hostname总是失败。

因此，我尝试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

然后我尝试

$ cat /etc/mail.rc 
alias root root<[email protected]>
alias username username<[email protected]>

但它仍然不起作用。有什么想法吗？

我也遇到了一些困难ssmtp。我学到的第一件事是别名机制才不是使用普通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.
[email protected]

# 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:[email protected]:mailhub.your.domain[:port]
# where [:port] is an optional port number that defaults to 25.
#
root:[email protected]
romano:[email protected]
postmaster:[email protected]

现在可以正常工作了：

test
