I don't know if this file comes from clam or amavis-new, but.... It contains the comment and command: # Run as a selected user (clamd must be started by root) User amavis Is this conf file for clam or amavis? As in /etc/clamd.conf we have: # Run as another user (clamd must be started by root for this option to work) # Default: don't drop privileges User clam # Initialize supplementary group access (clamd must be started by root). # Default: no AllowSupplementaryGroups yes Then in /etc/amavisd.conf (the real? conf file for amavis-new) in the Clamav section are comments: # # Note: run clamd under the same user as amavisd, or run it under its own # # uid such as clamav, add user clamav to the amavis group, and then add # # AllowSupplementaryGroups to clamd.conf; So is clam running under its user or amavis? Why is this last comment pointing to the 'old' clamav userid?
