Another possible explanation is that clamav will detect a lot of phishes, where sophos generally only detects viruses. Those phishes will also be detected as spam by spamassassin. So in effect, by pre-filtering phishing using clamd, you reduce the amount of spam, so spamassassin, which comes later (i presume?) will detect less spam. -- Jan-Pieter Cornet <[EMAIL PROTECTED]> !!
