Hi. Here's my problem (SERIOUS ONE). I have two servers (A and B). Both servers have ISPConfig 3 installed. ISPConfig Panel is on Server A. Both server has www and mail configured. I found SERIOUS BUG. If I send mail from SERVER A to SERVER B (via client or webpage) mail is DELIVERED to SERVER A! Even "GREETINGS MAIL" sended automaticly goes to SERVER A. I must say that my configuration assume that SERVER A is used to WEBPAGES and SERVER B as an MAILSERVER. Please HELP! Temporarly I solved this problem by adding in line (on both servers) additional_conditions = and active = 'y' and server_id=1 (where "1" is server id) in etc/postfx/mysql-virtual_domains.cf file. IHowever this is temporarly solution. It works but I dont know if it is proper for ISP and how long it will work (probably till id changes).
