I've installed a virtual mail system according to: http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu-10.04 Everything except quota and squirrelmail. I have a lot(1-3 per day) of false-positives in my spam quarantine folder, and 90% of those are because of bad header. (most bad header senders uses Outlook, no suprises there.) I dont want to quarantine bad header mails at all, i want them delivered to the recipients mail box! It would be ok to tag bad header mails in the subject, but definetley no quarantine. Settings in < /etc/amavis/conf.d/20-debian_defaults > Code: $final_virus_destiny = D_DISCARD; # (data not lost, see virus quarantine) $final_banned_destiny = D_REJECT; # D_REJECT when front-end MTA $final_spam_destiny = D_DISCARD; $final_bad_header_destiny = D_PASS; # False-positive prone (for spam) Settings in < /etc/amavis/conf.d/21-ubuntu_defaults > Code: $final_virus_destiny = D_DISCARD; # (defaults to D_BOUNCE) $final_banned_destiny = D_DISCARD; # (defaults to D_BOUNCE) $final_spam_destiny = D_DISCARD; # (defaults to D_REJECT) $final_bad_header_destiny = D_PASS; # (defaults to D_PASS), D_BOUNCE suggested i have not really understood what file is used: 21-ubuntu_defaults or 20-debian_defaults? And how do i make the bad header mails find there way to the recipient instead of quarantine? BTW, thanks for a very good guide, i really appreciate you guys taking your time to set up theese guides!
