I pretty much agree, yes.
I pondered it for a bit while reading mailname(5) and hostname(1).
I repushed it anyway since i see an improvments instead of just failing over.
Thanks though for fiding a system with more than 1 hostname, looks like all the
system i have access to have only one.

Now i wonder on the better action (granted that we should stay with
`hostname -f` output if that works), would it be better to
  1) strip `hostname -A` output to only consider the first result (is it
     sorted or otherwise stable on a system?)
  2) use a fixed string like "localhost". After all, that the /etc/mailname of
     a chroot...
Another way would be just copy the /etc/mailname of the host, the very same way
it's done for /etc/hosts, /etc/hostname and /etc/resolv.conf.


I welcome suggestions, otherwise I think i'll go with the last one, since i see
no drawback with it like i can do with the others.
