我已通过“Amavisd-new”将 SpamAssassin 集成到我的 postfix 邮件服务器上。
我面临的问题是，我生产邮件服务器上每 15 秒都会收到来自同一发件人、具有相同消息 ID 的同一封电子邮件，以下是我的 Postfix 日志：
Oct 25 01:11:02 g2t0433g postfix/smtpd[6497]: connect from webmail.warwick.net[204.255.24.104]

如何判断此类邮件是真实的邮件还是垃圾邮件？
我可以在 spamassassin 上设置任何规则来丢弃此类邮件吗？
目前我已将“peter***@warwick.net”添加到我的 postfix“main.cf”限制列表中，如下所示：
smtpd_recipient_restrictions =
check_sender_access hash:/etc/postfix/senderRestrictionList,
reject_unauth_destination,
reject_rbl_client zen.spamhaus.org,
reject_rbl_client bl.spamcop.net
permit
这是正确的方法吗？
请帮忙
提前致谢

如果您让邮件在服务器上排队（而不是拒绝它），您应该能够sudo postcat -q <message id>查看邮件及其标题。这应该可以让您确定它是否是垃圾邮件。
