postmap /etc/postfix/virtual postconf -n | grep virtual /etc/init.d/postfix reload #OR service postfix reload
/etc/postfix/virtual
@example.com info@example.net team@example.net ##forward catch all to two addresses info@example.info example@example.example
After changing execute:
postmap /etc/postfix/virtual
/etc/postfix/virtual_alias_domains
cat /etc/postfix/virtual_alias_domains example.info example.com example.net example.org
Address
cat /etc/postfix/vi main.cf.new myhostname = tango.info mydestination = localhost, $myhostname myorigin = /etc/mailname
cat /etc/postfix/main.cf myorigin = /etc/mailname mydomain = tango.info myhostname = tango.info

/etc/mailname
cat /etc/mailname example.info
OLD:
tango.info (CHANGE to anna.info - some email will now have smtp.mailfrom=xxx@anna.info Return-Path: <xxx@anna.info> From: xxx <xxx@anna.info> but message ID still 1234567890@tango.info )
mydomain
cat /etc/postfix/main.cf myorigin = /etc/mailname mydomain = example.info myhostname = example.info
OLD:
mydomain = tango.info myhostname = tango.info
CHANGE to anna.info - no influence?
myhostname
CHANGE to example.info - message-ID now 12345789@example.info
