In postfix, you can do this with virtual_alias_maps. You'll need a list of valid recipients. # main.cf relay_domains = example.com virtual_alias_maps = hash:/etc/postfix/virtual_alias transport_maps = hash:/etc/postfix/transport smtp_generic_maps = hash:/etc/postfix/generic # virtual_alias o...@example.com o...@old.example.com o...@new.example.com t...@example.com t...@old.example.com t...@new.example.com ... all users listed ... # transport old.example.com relay:[ip.of.old.server] new.example.com relay:[ip.of.new.server] # generic @old.example.com @example.com @new.example.com @example.com http://www.postfix.org/documentation.html -- Noel Jones
