# NOTE
# ----
# Virtual alias domains are used for forwading email from an email
# address to one or more other email addresses.  They cannot receive
# and save email, but only forward email somewhere else.
# The $virtual_alias_maps mapping contains forwarding (source,
# destination) of users or domains to other email addresses or entire
# domains.  This maps can return multiple right-hand side
# destinations (to forward to) for one left-hand side source, therefore
# one can forward copies of an email to several recipients.
