I'm sending email using Postfix on my Debian server, which is working fine.
Now I want to receive email by forwarding all incoming email to my email address (which is not on this server). I got this working using the following config:
/etc/postfix/virtual:
/.+@.+/ [email protected]
/etc/postfix/main.cf:
virtual_maps = regexp:/etc/postfix/virtual
This forwards all incoming email to my email address, which is working. However, this forwards email using the From header of the original email, which I don't want because it may get my IP address on a blacklist.
How can I rewrite the From header of all forwarded emails to something like [email protected]?
I tried using a regex to rewrite all domains that are not mine to [email protected], but since I'm not so good at regex I can't get it working. I also tried setting remote_header_rewrite_domain to my.domain but that doesn't change anything.
If possible, I would like to just set the Sender header for all forwarded emails.
