INSTALLATION
------------
Installing amavis in Fedora is simple. First, install the
amavis package:

  dnf -y install amavis

Don't be alarmed at the number of dependencies this installs.  This
package tries to be as full-featured as possible, including many
optional components for amavis.

Next, configure amavis to start on boot:

  systemctl enable amavisd.service

When you are ready, start the amavis service, it will also start
a clamd instance if available.

  systemctl start amavisd.service

Check /var/log/maillog for startup messages of amavis and clamd.
You can also check the journal.

  journalctl -a -u amavisd -u clamd@amavisd

The next step is to integrate amavis with your MTA.

POSTFIX
-------
The simplest method for enabling amavis support in postfix is to
use the content_filter configuration option to tell postfix to relay
mail through amavis using SMTP.  In this configuration, incoming
mail passes from postfix to amavis and back to postfix.  (Mail never
actually leaves the control of postfix however, since amavis does not
answer OK until it scans the message and transfers it back to postfix.
The worst that can happen is a failure at just the right time could
allow a message to be queued twice.)

Add the following to /etc/postfix/main.cf:

  content_filter = smtp:[127.0.0.1]:10024

You will probably also want to limit the number of postfix processes
to keep mail from coming in faster than it can be processed by adding
the following to /etc/postfix/main.cf:

  default_process_limit = 20

Add the following to /etc/postfix/master.cf:

  127.0.0.1:10025 inet n - - - 0 smtpd -o content_filter=

Be sure to read the TUNING section in README.postfix for information
on process limits.
