This is correct behaviour.
IYO, NMO ;-)
Sun's hostname command, iirc, uses the hosts table and is
well-documented[*]. You can have it return long names by default it you
like (reversing the order of entries following the IP address
in /etc/hosts may do it) but that's liable to break NIS or NIS+ if you
are using that.
I don't have a solaris box but you might try 'hostname -f' ...
I always use 'hostname -s' when I want the short name.

Using FQDN in, say, "helo" isn't an unfortunate linux novelty, it's a
requirement by RFC821/2821.
The point here really is that I'm trying to build code that is portable,
and possibly quite widely deployed. Futzing around with what hostname
returns on a given OS instance simply isn't an option. The real issue
here is that $self->qp->config(me) is ignoring the config/me file, and
appears to be unconditionally taking hostname. This will mostly be
unnoticable on Linux, where hostname does return the FQDN.
BTW: On solaris, the only argument hostname takes is if you want to
_set_ the hostname. "hostname -f" sets the hostname to "-f". So, don't
try that on Solaris at home folks ;-)
I'm not asking how to fudge Solaris config to return the FQDN, or how to
write a function that can return a FQDN (I can figure that out from
/etc/hosts), but how to get qpsmtpd to return the value I'd expect from
config(me). That will resolve various problems with generated Received
lines, log files, and a number of other things. Eg: plugins that call
Net::SMTP and want to set HELO and from lines etc.
As it stands, even tho qpsmtpd internally uses config(me), even if you
set config/me to your FQDN, qpsmtpd on Solaris generates invalid
Received lines, ala:
Received: from freebsd167.cost.it (HELO freebsd167.cost.it)
(213.156.62.167) by ertps004 (qpsmtpd/0.42rc1) ...
Log files have:
2008/02/13-23:59:58 ertps004[10709]:
ALL plugins that uses config(me) (eg: spamassassin, rcpt_ok,
queue/smtp-forward, various virus/*). get hostnames. queue/smtp-forward
emits invalid HELOs via Net::SMTP) etc. etc. etc.
