On Postfix, in the case of forwarding by aliases or .forward, if the forwarding results in an error, the error mail is sent to the original sender. The most easy way to prevent this behavior is setting the alias to a redirection to sendmail command and changing envelope sender address using sendmail -f option like below.<\/p>\n

| \/usr\/sbin\/sendmail -f <envelope sender address> <recipient address to forward>\r\n<\/pre>\n
Example:<\/p>\n
\/etc\/aliases<\/p>\n
foo: foo, \"| \/usr\/sbin\/sendmail -f bar xxx@example.com\"\r\n<\/pre>\n
sendmail -f option sets the envelope sender address. This is the address where delivery problems are sent to (\"bar\" in the above example). This means that an error mail is not delivered to the original sender.<\/p>\n
\u203b Be careful not to create infinite loop<\/strong>
\nIn the above example, you should be careful that foo does not come to be the last recipient.<\/p>\n
