4. Installation and integration

1) install and configure Postfix ClamAV

A) Installation

# Aptitude update

# Aptitude install Postfix ClamAV

B) Configure Postfix

# Nano/etc/Postfix/Main. cf

At the same time, add some content. The content of Main. Cf after configuration is complete is as follows:

The configuration file is modified, and the file corresponding to the newly added content in the configuration file is also created.

FindEnvelope_sender_header X-mailparts-fromAnd modify itEnvelope_sender_header X-yoursite-mailentries-from

Question 3:

# Nano/etc/spamassassin/mailmask. cf

Comment out the zero line of use_auto_whitelist

Question 4:

# Nano/opt/maildesk/ ETC/CONF. d/mymaildesk. Conf

Add the following content:

Virus scanners = ClamAV

Let's see if there are any problems in the log file.

# Tail-FN 100/var/log/mail. Log

To avoid this problem, you can thoroughly modify the/var/spool/Postfix directory permissions.

# Chmod 777-r/var/spool/Postfix

Check the log again and find everything is normal.
