Why send mail as user@myhostname, when the named host will never
ever receive email? You can avoid a lot of complication by using a
myorigin setting that specifies a domain name, and MX records for
that domain that point to a suitable mailhub.
myorigin = example.com
And perhaps even
relayhost = example.com
