我有一个 postfix + dovecot + spamassassin 设置，效果很好，但我想绕过垃圾邮件过滤的所有外发邮件（sasl 身份验证）。我肯定做错了什么，因为我已经permit_sasl_authenticated在我的系统中实现了它main.cf，但看起来它不起作用。
我的 main.cf 相关部分：
# SASL Auth for SMTP relaying
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_authenticated_header = yes
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtpd_sasl_local_domain = ...
broken_sasl_auth_clients = yes
# DKIM
milter_default_action = accept
milter_protocol = 6
smtpd_milters = unix:/var/run/opendkim/opendkim.sock
non_smtpd_milters = unix:/var/run/opendkim/opendkim.sock
# transports
dovecot_destination_recipient_limit = 1
local_recipient_maps = proxy:pgsql:/etc/postfix/pgsql/virtual_mailbox_maps.cf
virtual_transport = lmtp:unix:private/dovecot-lmtp
# restrictions
smtpd_relay_restrictions =
permit_mynetworks
permit_sasl_authenticated
defer_unauth_destination
smtpd_recipient_restrictions =
permit_mynetworks
permit_sasl_authenticated
reject_non_fqdn_hostname
reject_non_fqdn_sender
reject_non_fqdn_recipient
reject_unauth_destination
reject_unauth_pipelining
reject_unknown_recipient_domain
reject_unverified_recipient
reject_invalid_hostname
我的master.cf相关部分：
smtp inet n - y - - smtpd
-o content_filter=spamassassin
smtps inet n - y - - smtpd
-o content_filter=spamassassin
-o syslog_name=postfix/smtps
-o smtpd_tls_wrappermode=yes
-o smtpd_sasl_auth_enable=yes
-o smtpd_reject_unlisted_recipient=no
spamassassin unix - n n - - pipe
user=mail:mail argv=/usr/bin/spamc -u ${recipient} -e /usr/sbin/sendmail -oi -f ${sender} ${recipient}
如果我尝试使用选项main.cf插入所有内容，也无济于事。有什么解决方案可以实现这一点？没有使用其他过滤器，只有 DKIM。所以没有 amavis、clamav 之类的东西。master.cf-o
答案1
SASL 认证用户应使用smtps中定义的内容进行提交。您可以通过删除该部分中的master.cf行来删除 SMTPS 的内容过滤器。-o content_filter=spamassassin
