Expansion via virtual_alias_maps is limited to
virtual_alias_expansion_limit (default: 1000)
virtual_alias_recursion_limit (default: 1000)
When the limit is reached, cleanup(8) logs a warning, and
some recipients will not receive the mail.
With expansion via alias_maps, recursion is limit to 1000,
non-configurable. local(8) defers delivery when the limit is reached.
