KEI 的隨手雜記

起因 想要把一些廣告信的來源進行阻擋由不想誤檔正常的信件。 原理 Postgrey 的運作原理是讓 SMTP Server 在收到郵件後先回應 450 給來源 SMTP Server，若來源伺服器是正常的 SMTP Server 會在一段時間後自動重試，如果對方是使用發送垃圾郵件的工具不會將信件重送，如此可以達到有效阻擋垃圾郵件的目的。 安裝套件 postgrey-1.33-1.el4.rf.noarch.rpm perl-BerkeleyDB-0.43-1.el4.rf.i386.rpm perl-IO-Multiplex-1.10-1.el4.rf.noarch.rpm perl-Net-Server-0.99-1.el4.rf.noarch.rpm 參考下載位置  http://pkgs.org/ 設定 /etc/postfix/main.cf smtpd_restriction_classes = greylisting greylisting = check_policy_service unix:postgrey/socket smtpd_recipient_restrictions = ... check_client_access pcre:/etc/postfix/greylist ... /etc/postfix/greylist /(\-.+){4}$/ greylisting /(\..+){4}$/ greylisting # everything with 4 or more dots/hyphens in the hostname /(^|[0-9.x_-])(abo|br(e|oa)dband|cabel|(hk)?cablep?|catv|cbl|cidr|d?client2?|cust(omer)?s?|dhcp|dial?(in|up)?|d[iu]p|[asx]?dsld?|dyn(a(dsl|mic)?)?|home|in-addr|modem(cable)?|(di)?pool|ppp|ptr|rev|static|user|YahooBB[0-9]{12}|c[[:alnum:]]{6,}(\.[a-z]{3})?\.virtua|[1-9]Cust[0-9]+|AC[A-Z][0-9A-F...

起因 由於 POP3 的 services 常常被猜密碼覺得煩麻煩的，所以想要把這些猜密碼的位址阻擋。 安裝套件 fail2ban-0.8.4-23.el4.noarch.rpm ( http://www.fail2ban.org/wiki/index.php/Downloads ) gamin-0.1.7-1.4.EL4.i386.rpm (CentOS 4.6 CD#1) gamin-python-0.1.7-1.4.EL4.i386.rpm (CentOS 4.6 CD#3) shorewall-4.4.18-1.noarch.rpm ( http://www.shorewall.net/ ) 設定 /etc/fail2ban/jail.conf [dovecot-check] enabled = true filter = dovecot-check action = iptables-multiport[name=dovecot-check, port="pop3,pop3s,imap,imaps", protocol=tcp] logpath = /var/log/mail/dovecot ignoreip = 168.192.0.1 192.168.1.0/24 bantime  = 1800 findtime  = 300 maxretry = 3 /etc/fail2ban/fail2ban.conf logtarget = /var/log/fail2ban.log /etc/fail2ban/filter.d/dovecot-check.conf [Definition] failregex = (?: pop3-login|imap-login): .*(?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed).*rip=(?P<host>\S*),.* ignoreregex = 啟動 /etc/rc.d/ini...
