My problem: I own a postfix server with several Aliases on it. For example:
info@my.tld => abc@gmail.com
If I now send a email from def@gmail.com to info@my.tld it get's forwarded to abc@gmail.com
But then Google sees the information: From: def@gmail.com To abc@gmail.com , checks SPF and co and concludes: There is a mail coming from external with an internal address => must be SPAM.
SO: Is it possible to make postfix forward such mails as inline bounce or to use local a local From: ?
