My mailer daemon always gives away my internal IP address when I sending delivery errors.
email@example.com>: host mailserver.domain.com [192.168.*.*] said: 5545.4.0 Error: too many hops (in reply to end of DATA command)
How do I stop it from adding my IP address in the delivery failure.
Also, it send as firstname.lastname@example.org instaed of email@example.com
How do I rectify this too.
