不過有一樣野要留意：reject_non_fqdn_recipient 可能不能加入，因為程式會將個mail 交比 localhost 而如果加左呢一句，可能會由於這樣就discard 個mail 了。

vi /etc/amavis/conf.d/50-user

add a line (why?)

$daemon_group = 'clamav';
$mydomain = 'domain.com';
$myhostname = 'linux.domain.com';
$forward_method = 'smtp:[127.0.0.1]:10025';

vi /etc/dovecot/dovecot.conf

Modify the following lines.

protocols = imap imaps pop3 pop3s

vi /etc/passwd

Add amavis to clamav group, and add clamav to amavis group
