Hi to all, i have a question about a particular postfix configuration. In my test machine, i try to create a particular enviroment. I have one postfix istance that bind in 0.0.0.0:25 and in this postfix istance i use a relay_domains and relay_transport to redirect all mail from one domain to another postfix instance that bind in localhost:2525. For example:
relay_domains = example.com relay_transport = smtp:localhost:2525 The second istance is use to manage the users and other particular condition, and in my configuration would that this istance is separate for my first instance. Now it works very well, but there is a problem. If my second postfix istance (localhost:2525) return for example Error 554 or Error 551 after "rcpt to" command, my first postfix instance, send the notification for bounce. This isn't very well because i could be attacked form spammer. My question specifically is: " Can i configure my fisrt istance to proxy all SMTP comunication only for one domain??" Else, For you is there another mode to configure my enviroment? Thanks to all and sorry for my bad English ;-)
