Hello. My mail server received unsollecited emails with header From: similar to 'Heidi <info>'.
Users perceive that email comes from our company as the header From: has been rewrite in 'Heidi <i...@host.domain.tld>'. Infact: myorigin = $mydomain mydomain = host.domain.tld and append_at_myorigin = yes local_header_rewrite_clients = permit_inet_interfaces Is there a way to block incoming e-mails whose 'Header From:' does not specify valid email address? Regards, RS
