如何更改后缀的默认电子邮件地址? [英] how to change default email address for postfix?
问题描述
我有一个运行python，php，perl，ruby的服务器，并且我还有几个也会发送邮件的应用程序.我想知道是否其中一个应用程序未指定发件人电子邮件地址，发件人电子邮件地址设置为http@example.com，发件人名称为"http".
I have a server running python, php, perl, ruby, and I have couple applications which also send mail. I was wondering in case if one of the applications don't specify a from email address, the sender email address is set to http@example.com and the sender name was "http".
我可以通过进入/etc/passwd并将其更改为所需的名称来更改发件人名称，但是如何将http@example.com更改为admin@example.com?
I was able change the sender name by going into /etc/passwd and changing the name to what I wanted, but how do I change http@example.com to admin@example.com?
推荐答案
您可以使用 smtp_generic_maps 重写外发smtp邮件的电子邮件标头:
You can use the smtp_generic_maps of postfix to rewrite email headers for outgoing smtp mail:
user:~$ echo "http@example.com admin@example.com" >> /etc/postfix/generic
user:~$ echo "smtp_generic_maps = hash:/etc/postfix/generic" >> /etc/postfix/main.cf
user:~$ postmap /etc/postfix/generic
user:~$ service postfix restart
