"." at the end of FQDN is common convention when entering FQDN name as
used by dnsadmins.
It isn't just a common convention:
RFC1034:
"When a user needs to type a domain name, the length of each label is
omitted and the labels are separated by dots ("."). Since a complete
domain name ends with the root label, this leads to a printed form which
ends in a dot."
RFC1035:
"Domain names that end in a dot are called
absolute, and are taken as complete. Domain names which do not end in a
dot are called relative; the actual domain name is the concatenation of
the relative part with an origin specified in a $ORIGIN, $INCLUDE, or as
an argument to the master file loading routine. A relative name is an
error when no origin is available."
"ws." is a FQDN. "listbox.com" is not (unless it is made clear that an
implicit $ORIGIN of "." is to be considered).
Forget what rfc2821 says. Intentional or not, it _is_ a bug.
