Well, yes, if the supporting module is not taint-safe, Qpsmtpd won't work. I have no idea why this particular line should be throw a taint error (in my copy of utf8_heavy.pl, line 156 is empty and nothing around there seems to be using anything external). It is possible that whatever was being fed to that routine should have been untainted by some other code, so the actual problem may be elsewhere.
You should upgrade a newer version of Perl for many reasons (5.8.5 is almost out, but 5.8.4 is just fine), not just the likelyhood that your tainting problems will be gone.
