EC2 Guide: Software Configuration from existing EBS volumes (6b / 7)
This page is designed for the re-attachment of existing EBS volumes previously created by completing this whole guide. If you do not have these 3 EBS volumes with all data configured on them you are on the wrong page and should use the contents below!
ClamAV will be our anti-virus system and is very easy to set-up! We just need to update some permissions:
sudo adduser clamav amavis sudo adduser amavis clamav
SpamAssassin's function is given away by it's name. We will use this for spam filtering our e-mails.
sudo nano /etc/default/spamassassin
[...] ENABLED=1 [...] CRON=1 [...]
We need to create a razor config file for it to work:
sudo razor-admin -create
Start the service:
sudo service spamassassin start
Amavisd-New will be our interface between our mail transport program (Postfix) and our spam and virus filters (SpamAssassin / ClamAV).
sudo nano /etc/amavis/conf.d/15-content_filter_mode
Uncomment the spam and anti-virus lines.
use strict; # You can modify this file to re-enable SPAM checking through spamassassin # and to re-enable antivirus checking. # # Default antivirus checking mode # Uncomment the two lines below to enable it # @bypass_virus_checks_maps = ( \%bypass_virus_checks, \@bypass_virus_checks_acl, \$bypass_virus_checks_re); # # Default SPAM checking mode # Uncomment the two lines below to enable it # @bypass_spam_checks_maps = ( \%bypass_spam_checks, \@bypass_spam_checks_acl, \$bypass_spam_checks_re); 1; # insure a defined return
Some fairly key definitions are missing because they are not "free" - thanks Ubuntu. Enable / uncomment them!
sudo nano /etc/amavis/conf.d/01-debian
[...] $unfreeze = ['unfreeze', 'freeze -d', 'melt', 'fcat']; [...] $lha = 'lha'; [...]
Amavis needs permissions here:
sudo chmod -R 775 /var/lib/amavis/tmp
sudo service amavis restart
Configure Mail Logging
Because we mounted parts of our file system through EBS volumes we need to update the mail log locations.
sudo nano /etc/rsyslog.d/50-default.conf
[...] mail.* -/var/log/postfix/mail.log [...] mail.info -/var/log/postfix/mail.info mail.warn -/var/log/postfix/mail.warn mail.err /var/log/postfix/mail.err [..]
sudo service rsyslog restart
Restart Postfix / Dovecot
Make sure that Amavisd-New is plugged in correctly:
sudo service postfix restart sudo service dovecot restart
