Hi, I'm using postfix as mail server and I'm very satisfied about how it works.... I've to implement a service that sends lists of mails including commercial offers (and no spam obviously)... the problem is that sometimes some Internet providers recognize servers that sends too much mail and can ban them...
For example, I know that a particular ISP doesn't want to receive more than 30 email a day... so I need to create a service that can implement a different behaviour depending on the receiver mail server or ISP that manage it.... Have I to create it myself ? Does exist something that allows to set such rules?
