Hello, is it possible to perform dns query before checking domains maps?
My users can add entries to virtual domains map and alias maps. I want to avoid scenario that someone adds gmail.com domain and catch outbound mails for gmail.com. Second solution I figured out is to make relay_host to other server which doesn't have any domains maps. But the problem is the same, postfix on the first server checks domains_maps before relaying message. I will appreciate any hints. Thanks in advance. -- M.
