cat /etc/postfix/virtual_alias_domains

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/postfix/main.cf

cat /etc/postfix/main.cf (partial):

myorigin = /etc/mailname
mydomain = example.info
myhostname = example.info
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
virtual_alias_domains=/etc/postfix/virtual_alias_domains
virtual_alias_maps=hash:/etc/postfix/virtual

/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 = tango.info
myhostname = tango.info

CHANGE to anna.info - no influence?

myhostname

CHANGE to anna.info - message-ID now 12345789@anna.info
