There are a *lot* of questions about bulk emailing.   I was trying to find one to close https://serverfault.com/questions/515377/linux-mail-server-architecture-for-bulk-mailing as, but didn't find anything.. specifically canonical..

Here's an idea.

**Q:**
My $employer wants to be able to send massive amounts of email, what's the best way to achieve this.
**A:**
