Those crazy guys over at NetBSD have removed Sendmail from the core. I had a chat with the NetBSD security officer on the issue. Interesting. The MTA remaining in core will be Postfix (of which I am a big fan). I think it’s an excellent decision. I actually don’t think it goes far enough though - why have an MTA in the core at all? Most hosts simply don’t need the full capaibilities of an SMTP daemon. They simply need to send mail. So use a cut- down binary that does just that and make all the MTAs available as packages.
