我已经安装了 SpamAssassin 并将其配置为从 sql 读取首选项。我意识到它没有读取用户的首选项，并检查了我看到spamc客户端发送的所有请求都作为 spamd 用户执行的日志。
这是 spamc 客户端如何按照master.cf文件中的配置执行（后缀）：
spamassassin unix - n n - - pipe
user=spamd argv=/usr/bin/spamc -f -e
/usr/sbin/sendmail -oi -f ${sender} ${recipient}
我添加-u ${recipient}到 spamc，并在日志中看到它有效，现在用户的首选项已正确获取。
但是，这种方式会破坏我对别名的传递。
考虑[email protected]成为[email protected]和 to的后缀别名[email protected]。添加上述内容-u会spamc导致电子邮件无法发送到别名。
当它不发送电子邮件时，这里有很多后缀：
Feb 14 21:12:36 mail postfix/qmgr[51620]: 6EFD11003F5: from=<[email protected]>, size=2588, nrcpt=2 (queue active)
Feb 14 21:12:37 mail postfix/pipe[51637]: 6EFD11003F5: to=<[email protected]>, orig_to=<[email protected]>, relay=spamassassin, delay=1.3, delays=0.03/0/0/1.3, dsn=2.0.0, status=sent (delivered via spamassassin service (X-Spam-Level: X-Spam-Status: No, score=-1.9 required=3.0 tests=BAYES_00,SPF_HELO_PASS autolearn=ha))
Feb 14 21:12:37 mail postfix/pipe[51637]: 6EFD11003F5: to=<[email protected]>, orig_to=<[email protected]>, relay=spamassassin, delay=1.3, delays=0.03/0/0/1.3, dsn=2.0.0, status=sent (delivered via spamassassin service (X-Spam-Level: X-Spam-Status: No, score=-1.9 required=3.0 tests=BAYES_00,SPF_HELO_PASS autolearn=ha))
Feb 14 21:12:37 mail postfix/qmgr[51620]: 6EFD11003F5: removed
我删除了-u ${recipient}, 事情又可以工作了，但我无法从以下日志中找到太多帮助：
Feb 14 21:14:36 mail postfix/master[51877]: daemon started -- version 3.4.13, configuration /etc/postfix

spamassassin 日志，当它不起作用时，是这些：

当它工作正常时，如下所示：

关于为什么会发生这种情况的任何线索？这里明显的区别是，在 spamassassin 日志上，当它不起作用时，我们看到它spamc是由用户调用的[email protected]（而不是 with[email protected]和 not with [email protected]）。别名所代表的收件人都没有收到电子邮件。在第二次尝试时，没有-u参数，然后 spamc 被执行而不发送用户名（失败进入默认spamd用户），并且邮件被传递给用户a和b.
可以sendmail吗？
最好的，

我想我修好了。添加
spamassassin_destination_recipient_limit = 1到main.cf（后缀）就可以了。
