Previously, only postfix-relaymap.cf and postfix-accounts.cf would be
used to populate the relayhost_map file.
Now, also use postfix-virtual.cf when present. To me, there is nothing
absurd about sending mail "From:" a virtual account (or more
specifically its domain) so it makes sense that when a $RELAY_HOST is
defined it should be used for virtual accounts as well.
