forward emails to non existing accounts to one central one in Postfix
I have a (Linux) server running with Postfix as an email server. When registering to a new site I do not want to use a single mail twice so when my email gets leaked by a security breach at any site only this one mail get published in lists to the internet, but because I only used it on that site it would be useless. By this meaning, I would always have to create a new email user whenever I sign up to a site and I would also have to enable email forwarding to the “main” email (having a ton of addresses is not an option). As I am lazy I do not want to do this so I am looking for a way to automatic forward emails to a specified account when the recipient’s email would be on my server but does not exist.
best regards Thore
