Inbound SMTP relay with Haraka

in flag

enter image description here

I would like to know if the following scenario is possible to achieve with Haraka (employing existing plugins).

There is a public SMTP server (let's call it a Gateway) that accepts inbound e-mails sent to any user at *.mail.domain (note the subdomain wildcard - the MX record is configured so it points to Gateway IP address) and relays it to the appropriate SMTP server (let's call it a Satellite) in the private network (MX records are not set for satellites). The relaying is done based on the recipient domain. The satellite servers are dynamic in the sense that they join/leave the private network dynamically so they are not known beforehand.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
