我正在尝试使用 重写TO:已发送的电子邮件中的标题ssmtp。
我已将邮件配置为root通过 发送ssmtp（通过在 处创建符号链接/etc/sendmail）。
它被重定向到/etc/aliases条目，但 TO：标头始终是用户本身，在本例中为“TO：root”。
SMTP 服务器拒绝此别名。我想将 TO: 字段重写为可配置的电子邮件地址。
我已经配置了：/etc/aliases，，/etc/ssmtp/revaliases并且/etc/ssmtp/ssmtp.conf正如我所料可以工作。
这可能吗ssmtp？

设置：
yum -y install ssmtp
service sendmail stop
chkconfig --levels 2345 sendmail off
chkconfig --del sendmail
export tmpsm=$(which sendmail)
mv $tmpsm $(echo $tmpsm.bak)
ln -s $(which ssmtp) $tmpsm
groupadd nogroup
useradd ssmtp -g nogroup -s /sbin/nologin -d /nonexistent -c "sSMTP pseudo-user"
chown ssmtp:wheel /etc/ssmtp/ #http://en.wikipedia.org/wiki/Wheel_(Unix_term)

chown ssmtp:nogroup $(which ssmtp)
chmod 4555 $(which ssmtp)

测试：
yum -y install mailx
#test baseline:
echo "test" | mail -v -s "$(date)" [email protected]
#test sending to a local user:
echo $(netstat -apn | grep :) | mail -v -s "$(date)" root #<-------------------FAILS to send due to SERVER specific policy! because "TO: root"
#check logs:
