要使用ClamAV扫描邮件,您需要安装并配置ClamAV及其相关组件。以下是在Ubuntu上使用ClamAV扫描邮件的步骤:
- 首先,安装ClamAV和ClamAV的邮件扫描插件:
sudo apt-get update sudo apt-get install clamav clamav-daemon clamav-freshclam clamav-milter
- 更新病毒数据库:
sudo freshclam
- 配置ClamAV邮件扫描插件。在
/etc/clamav/clamd.conf
文件中添加以下行:
MilterSocket /var/spool/postfix/clamav/clamav-milter.ctl ClamdSocket unix:/var/run/clamav/clamd.ctl
- 启动ClamAV服务:
sudo systemctl start clamav-daemon sudo systemctl start clamav-freshclam
- 配置邮件服务器以使用ClamAV扫描邮件。这里以Postfix为例,编辑
/etc/postfix/main.cf
文件并添加以下配置:
content_filter = scan:[127.0.0.1]:10025 receive_override_options = no_address_mappings
- 在
/etc/postfix/master.cf
文件中添加以下行:
scan unix - - n - 16 smtp -o smtp_send_xforward_command=yes -o disable_mime_output_conversion=yes -o smtp_generic_maps= 127.0.0.1:10025 inet n - n - 16 smtpd -o content_filter= -o receive_override_options=no_unknown_recipient_checks,no_header_body_checks -o smtpd_helo_restrictions= -o smtpd_client_restrictions= -o smtpd_sender_restrictions= -o smtpd_recipient_restrictions=permit_mynetworks,reject -o mynetworks=127.0.0.0/8 -o smtpd_authorized_xforward_hosts=127.0.0.0/8
- 重新加载Postfix配置:
sudo systemctl restart postfix
现在,您已经配置好了使用ClamAV扫描邮件的环境。您可以通过发送一封包含病毒的邮件来测试是否ClamAV成功扫描邮件。
