Hello, yesterday night my Djigzo running out of space, not really, 350 MB free, but it stops delivering emails and and try to send a notification. So after I free space, there were 33000 notification pending and so the system still does not work correctly. The problem is, it sends the notification to postmaster(a)srv-bn-segw01.yyy.com and not to postmaster(a)yyy.com, so they bounced. So I created the domain srv-bn-segw01.yyy.com and after a few hours, I got my emails coming still the crash exists. First question, where can I change the address postfix is sending his alerts? Second question is, after I deleted many logs, there is still much less space free, then before. Any idea where I can make more free space? Last question is, did anyone manage to sync certificates between two machines, to get a automatic backup server via MX record? Thanks for your help. Marc
