It depends on what you do with the mail.  If you discard or
reject spam or spam scoring above a threshold, then it's almost
certainly cheaper to spam-scan first.  If you're only tagging spam
but throwing away viruses, it's probably cheaper to virus-scan first.
The fact that clamd has phishing signatures muddies the waters a bit;
there may be some "viruses" that are really spam.
