Hello, I want to configure postfix to make it able to send emails from different IP addresses (all of them bound on one server). Right now I have a working postfix+courier+sasl, but I need it to send the email from the IP that it receives the connection. For example: There are 3 ip addresses bound on a 3 virtual interfaces (192.168.10.1 .2 and .3). When a user tries to send an email connecting to 192.168.10.3, is it possible for postfix to send the email from that IP (not from .1 or whatever the physical interface is)?
I know this is possible by creating clones (with small config modification) of postfix, but this won't do the job for me since I want to install aprox 200 of this interfaces. I'm running (the company that I work for) a website with fashion campaigns and it sends more than 50K emails each day, 90% of them being hosted by Yahoo (all users being registered, so this is not spam) and I'm sure that you are aware of Yahoo's policies. I tried to use throttling solutions (send 2 emails per second or even less), the messages are still deferred after some time. So my last option before buying some service from inxmail or mailchimp is to try this, but I cannot implement it (google is not my best friend in this case). Did someone made it work? If yes, can you give me a tip (I'm not asking for the full solution).
