My /var/spool/mqueue.in holds all messages when I set "Virus Scanners = clamav" in /etc/MailScanner/MailScanner.conf. If I set "Virus Scanners = none" and restart MailScanner, the mail flows well. Did I miss something somewhere in the Clam or MailScanner config? Thanks! Red Hat 7.1 MailScanner 4.11-1 Clam 0.54
