I thought this would be accomplished by putting "foo.myohiovalley.net
<http://foo.myohiovalley.net>" in virtual_alias_domains and mapping
"foo.myohiovalley.net <http://foo.myohiovalley.net>" to
"myohiovalley.net <http://myohiovalley.net>" in virtual_alias_maps. But
that isn't happening as expected. I tried mapping an actual user
"xy...@foo.myohiovalley.net <mailto:xy...@foo.myohiovalley.net>" to
"xy...@myohiovalley.net <mailto:xy...@myohiovalley.net>" and that
actually did work. But I want to do this by domain name only so I don't
end up with <number_of_domains> times <number_of_users> mapping entries.
The correct way to do this is a 1-1
u...@foo.example.com u...@example.com
mapping. Use a script to generate the required tables and
don't worry about the number of entries.
While postfix does support wildcard domain > domain rewriting,
it is highly discouraged because it disables recipient
validation -- that tends to fill your queue with undeliverable
mail and will get you blacklisted as a backscatter source.
As an alternative, you may be able to use smtp_generic_maps to
rewrite the destination domain on the fly during delivery. See:
