Use AMAVISD-NEW + SOPHOS to scan mail viruses

Article Title: Using AMAVISD-NEW + SOPHOS to scan mail viruses. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
　　 Note:
1. My POSTFIX is included in the installation system, so I didn't introduce its installation method, so I hope it will not be troublesome.
2. SOPHOS is a commercial software. If it is used for commercial purposes, you need to pay for it ......
3. the email server configuration is troublesome. Please do not expect this article to be available in one step. I can only wish you good luck ~

1. Install PERL MODULES
========================================================== ==========
(Perl version 5.005 or later is required)
Check the INSTALL in the installation package. Generally, all the listed MODULES must be installed:
Quote:

Archive: Tar (Archive-Tar-x.xx)
Archive: Zip (Archive-Zip-x.xx)
Compress: Zlib (Compress-Zlib-x.xx)
Convert: TNEF (Convert-TNEF-x.xx)
Convert: UUlib (Convert-UUlib-x.xxx)
MIME: Base64 (MIME-Base64-x.xx)
MIME: Parser (MIME-Tools-x.xxxx)
(The patched MIME-tools by David F. Skoll is recommended over 5.411,
As it better handles broken/bad MIME syntax:
Http://www.mimedefang.org/-> Download section)

> Install Net: SMTP
　　
Method 2 (complicated)
Here: http://www.perl.com/CPAN-local/modu...ules.index.html
Download the related installation software package and decompress and install it one by one.
　　
2. Install AMAVISD-NEW
========================================================== ==========
-Create a user group and a user named amaivs. You can also use other names to run AMAVISD.
　　
-Create the/var/amavis directory, change the owner to amavis, and change the Directory attribute to 750, that is:
Mkdir/var/amavis
Chown amavis: amavis/var/amavis
Chmod 750/var/amavis
　　
-Copy/usr/tmp/amavisd to/usr/local/sbin/, set the attribute to 755, and set everyone to root.
　　
-Copy/usr/tmp/amavisd. conf to/etc/, set the attribute to 755, and set everyone to root.
　　
-Create the/var/virusmails/directory, set the attribute to 750, and set all people and groups to amavis.
　　
-Edit/etc/amavisd. conf based on local conditions, which is mainly the variable settings in Section I, for example:
$ Daemon_group, $ daemon_user, $ MYHOME, $ TEMPBASE, $ QUARANTINEDIR, $ mydomain
　　
-In Section VII of the/etc/amavisd. conf file, if the "clamav" option is commented out by "#", remove the annotator.
　　
-Use the "debug" attribute to start amavisd and check whether the system has any error message:
/Usr/local/sbin/amavisd debug
　　
-If it is normal, you can use "/usr/local/sbin/amavisd stop/start" to close and open the service.
2. Use POSTFIX
========================================================== ==========
-Edit/etc/postfix/master. cf and add:
Smtp-amavis unix--y/n-2 smtp
-O smtp_data_done_timeout = 1200
-O disable_dns_lookups = yes
　　
127.0.0.1: 10025 inet n-y/n-smtpd
-O content_filter =
-Edit/etc/postfix/main. cf and add:
Content_filter = smtp-amavis: [127.0.0.1]: 10024
　　
-Make sure that AMAVISD is enabled and restart POSTFIX:
Postfix reload
　　
At this time, if the installation is successful, the mail system will already have the anti-virus function. You can send a letter with a virus to test the content of the mail:
X5O! P % @ AP [4 \ PZX54 (P ^) 7CC) 7 }$ EICAR-STANDARD-ANTIVIRUS-TEST-FILE! $ H + H *
　　
　　 Additional instructions
========================================================== ==========
-By default, all toxic and junk emails detected by the system are archived under/var/viursmails /.
-To disable the anti-virus function, you only need to comment out content_filter = smtp-amavis: [127.0.0.1]: 10024 in/etc/postfix/main. cf.
