More about ClamAV Postfix<\/h2>\n

ClamAV is mainly designed to scan the files in the server. It detects viruses and any malicious contents from the emails and files in the server.<\/p>\n

It also scans the archive files, zip files and many more.<\/p>\n

ClamAV integrated with Postfix will scan all the emails on the server.<\/p>\n

Now, let\u2019s see how our\u00a0Support Engineers<\/a>\u00a0install ClamAV.<\/p>\n

 <\/p>\n

How we install ClamAV Postfix<\/h2>\n

Here is the simple installation steps for ClamAV in Postfix in Ubuntu that our\u00a0Support Engineers<\/a>\u00a0follow.<\/p>\n

1. Initially, we run the below command to download and install ClamAV.<\/p>\n

apt-get install clamav clamsmtp clamav-freshclam<\/code><\/pre>\n
2. Next, we edit the configuration file\u00a0\/etc\/clamsmtpd.conf<\/em>. Here, we update the below lines from<\/p>\n
OutAddress: 10025\r\nListen: 1xx.x.x.1:10026<\/code><\/pre>\n
to<\/p>\n
OutAddress: 10026\r\nListen: 1xx.x.x.1:10025<\/code><\/pre>\n
3. Then, we edit the postfix configuration file\u00a0\/etc\/postfix\/main.cf<\/em>\u00a0and add the below contents<\/p>\n
content_filter = scan:1xx.x.x.1:10025\r\nreceive_override_options = no_address_mappings<\/code><\/pre>\n
4. Also, we edit the\u00a0\/etc\/postfix\/master.cf<\/em>\u00a0file and add the below contents<\/p>\n
# AV scan filter (used by content_filter)\r\nscan unix - - n - 16 smtp\r\n-o smtp_send_xforward_command=yes\r\n# For injecting mail back into postfix from the filter\r\n1xx.x.x.1:10026 inet n - n - 16 smtpd\r\n-o content_filter=\r\n-o receive_override_options=no_unknown_recipient_checks,no_header_body_checks\r\n-o smtpd_helo_restrictions=\r\n-o smtpd_client_restrictions=\r\n-o smtpd_sender_restrictions=\r\n-o smtpd_recipient_restrictions=permit_mynetworks,reject\r\n-o mynetworks_style=host\r\n-o smtpd_authorized_xforward_hosts=1xx.x.x.0\/8<\/code><\/pre>\n
5. Lastly, we restart postfix, ClamAV-daemon, and clamsmtp.<\/p>\n
Finally, we have configured ClamAV.<\/p>\n
