ubuntu下安装设置amavis和clamav

注意内存在3G或更小内，请只安装amavis,4G以上可以考虑安装clamav,否则会卡死
一、升级系统

apt-get update -y
apt-get upgrade -y

二、安装配置amavis
2.1安装amavis和支持组件

apt-get install amavisd-new -y
apt-get install arj cabextract cpio rpm2cpio file gzip lhasa pax rar unrar p7zip-full unzip zip lrzip liblz4-tool lzop unrar-free nomarch bzip2 lzip

2.2配置amavis
编辑/etc/amavis/conf.d/05-node_id文件取消注释,注意换成你自己的域名
$myhostname = "mail.loshub.com";
2.3、集成到postfix上去
2.3.1编辑/etc/postfix/main.cf在最后面的下一行加入以下内容

#amavis
content_filter = smtp-amavis:[127.0.0.1]:10024
smtpd_proxy_options = speed_adjust

2.3.2编辑/etc/postfix/master.cf文件在最后面的下一行加入以下内容

smtp-amavis   unix   -   -   n   -   2   smtp
     -o syslog_name=postfix/amavis 
     -o smtp_data_done_timeout=1200
     -o smtp_send_xforward_command=yes
     -o disable_dns_lookups=yes
     -o max_use=20
     -o smtp_tls_security_level=none
127.0.0.1:10025   inet   n    -     n     -     -    smtpd
     -o syslog_name=postfix/10025
     -o content_filter=
     -o mynetworks_style=host
     -o mynetworks=127.0.0.0/8
     -o local_recipient_maps=
     -o relay_recipient_maps=
     -o strict_rfc821_envelopes=yes
     -o smtp_tls_security_level=none
     -o smtpd_tls_security_level=none
     -o smtpd_restriction_classes=
     -o smtpd_delay_reject=no
     -o smtpd_client_restrictions=permit_mynetworks,reject
     -o smtpd_helo_restrictions=
     -o smtpd_sender_restrictions=
     -o smtpd_recipient_restrictions=permit_mynetworks,reject
     -o smtpd_end_of_data_restrictions=
     -o smtpd_error_sleep_time=0
     -o smtpd_soft_error_limit=1001
     -o smtpd_hard_error_limit=1000
     -o smtpd_client_connection_count_limit=0
     -o smtpd_client_connection_rate_limit=0
     -o receive_override_options=no_header_body_checks,no_unknown_recipient_checks,no_address_mappings

2.4加入系统启动amavis

systemctl enable amavis
systemctl start amavis

amavis安装完成了
三、安装clamav程序

apt install clamav clamav-daemon -y
systemctl restart clamav-daemon
adduser clamav amavis

编辑
/etc/amavis/conf.d/15-content_filter_mode，取消以下注释

@bypass_virus_checks_maps = ( 
      /%bypass_virus_checks, /@bypass_virus_checks_acl, /$bypass_virus_checks_re);

systemctl restart amavis clamav-daemon
