Clam AV

Well after working through issues with the clamav install, I have come to an impass with postfix. When I append the code given in the article to the master.cf file I get errors when attempting to start postfix. Here is the code: smtp-amavis unix - - y - 2 smtp -o smtp_data_done_timeout=1200 -o disable_dns_lookups=yes 127.0.0.1:10025 inet n - y - - smtpd -ocontent_filter= -olocal_recipient_maps= -osmtpd_helo_restrictions= -osmtpd_client_restrictions= -osmtpd_sender_restrictions= -omynetworks=127.0.0.0/8 Sep 5 10:08:58 postal postfix/master[14138]: fatal: /etc/postfix/master.cf: line 109: bad transport type: smtp_data_done_timeout=1200 This error occurs in different as you comment out the offending lines. So my question is, where in the master.cf file should this code go? I have tried the top, the middle and the bottom. Anyone have any ideas?
