vi /etc/dovecot.conf

protocols = pop3
ssl_disable = yes

修改dovecot收信預設位置

chkconfig --level 3,5 amavisd on

指定郵件伺服器網域

vi /etc/amavisd/amavisd.conf

$mydomain = 'shsps.kh.edu.tw'

在 master.cf 中先定義一個病毒過濾服務

vi /etc/postfix/master.cf

再加入底下幾行設定

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

    -o smtpd_restriction_classes=
    -o smtpd_client_restrictions=
    -o smtpd_helo_restrictions=
    -o smtpd_sender_restrictions=
    -o smtpd_recipient_restrictions=permit_mynetworks,reject
    -o mynetworks=127.0.0.0/8
    -o strict_rfc821_envelopes=yes
    -o smtpd_error_sleep_time=0
    -o smtpd_soft_error_limit=1001
