At some point, I really have to write about the new whatthefuck.com mail architecture. It is made up of some pretty epic hacks, but the new system is one hundred times more reliable and versatile than the old system.
Okay, I suppose that isn't saying much.
I do have to say this. I started out building on top of a courier/postfix based system, and ended up rolling my own on top of qpsmtpd, and will be writing a custom IMAP daemon for the newly-created system. The first version is very basic, but there are so many neat things I can do with it.
The new server with a terabyte and a half of space is heading to the data center this week, but if this works how I hope, there may be a few more servers heading over there soon enough. FreeBSD and ZFS is pretty much admin-heaven. PostgreSQL is a wonderful thing as well.
