Hello, I try to setup address rewriting with /etc/mail/genericstable and /etc/mail/virtusertable on my mail-relay with sendmail 8.11.0. I have an internal host, which has configured as SENDMAIL-RELAY my mail-relay, the variable FROM-HEADER is empty. My mail-relay is connected to the Internet, the FROM-HEADER ist set to "mydomain". I've configured a file genericstable and virtusertable like this. /etc/mail/genericstable: usr1@host1.mydomain usr1@mydomain /etc/mail/virtusertable: usr1@mydomain usr1@host1.mydomain The problem ist, if I send a mail from the internal host to the internet, the from-address is not rewrited, but if I send a mail from the Internet to "usr1@mydomain" the address is rewrited to usr1@host1.mydomain. All internal mail from usr1@host1.mydomain to usr2@host2.mydomain should not be rewrited. The address rewriting works only for incoming mail, not for outgoing. Any ideas? Thanks, Robert
