<off>I slept some hours, my mind is relaxed and less confused than those last days, let's go ! ;o)</off>
Thanks to Wietse and mouss, my gateway is now fully functional, and relays emails to my server : Internet --> mx1.mydomain.com[my gateway with postfix] --> mx2.mydomain.com (only MX1 acts as a DNS MX for all emails sent to mydomain.com) First goal is achieved. Next step (in a few month) will be to migrate our mx2 email server from Lotus Notes to mx1, which will be in a few month our final email sever. Then I'm searching for the right solution not only to forward emails to mx2, but to store all of them (dovecot) on mx1 in Maildir format. Actually, I did not find any answer on the subject. Either emails are relayed, either they are stored ... Is it possible, and what is the nicest native solution according to such a configuration please ?
