I'm not sure what the above arguments to 'host' are supposed to do, but the conclusion you've drawn is incorrect. The fact that the debian.org A record points to the same place as the klecker.debian.org A record does /not/ mean that 'mail is the same': $ dig debian.org mx ; <<>> DiG 9.1.0 <<>> debian.org mx ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 39344 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 3, AUTHORITY: 9, ADDITIONAL: 10 ;; QUESTION SECTION: ;debian.org.

So mail for klecker goes to klecker, but mail for debian.org goes to /master/. Also, even if the final MX for klecker.debian.org and debian.org was the same, remote mail servers should not be rewriting mail addresses for one and turning them into the other! Imagine the havoc this would play on mail servers that do virtual-hosting of email for multiple domains. Steve Langasek postmodern programmer
