# postconf myorigin

Should I just change "mail name" during postfix debconf questions to
"comcast.net" ?? Mail will then appear to come from
[accountname]@comcast.net or root@comcast.net which are not real emails.
It looks like I need to modify virtual(5) or canonical(5) but I cannot
grok the examples from postfix-doc. aliases(5) seems to be okay; it's
correctly delivering local root mail to my account.
