All mail is mine
While I’m doing web development I want to have an email server that ensures that
all mail will end up in my mailbox. To this end I set up Postfix with this rule
header_checks = regexp:/etc/postfix/header_checks.regexp
header_checks.regexp then contains:
/^To:/ REDIRECT email@example.com
This results in all mail being sent via my SMTP server is delivered to my mailbox, regardless of who it’s intended for.
