Dovecot反垃圾邮件插件不会被触发

Question

我对使用dovecot2.1.7和d垃圾邮件3.10.1的反垃圾邮件插件有一个问题。

我认为，反垃圾邮件插件不识别垃圾文件夹，因为日志报告。

Mar 25 13:11:22 mail imap: antispam: mailbox_is_spam(Junk): 0

在Google上发现很少的结果之后，我敢肯定，输出应该是

Mailbox_is_spam(垃圾)：1

dovecot反垃圾邮件配置如下：

protocol imap {
  mail_plugins = $mail_plugins antispam
}


plugin {
  antispam_debug_target = stdout
  antispam_verbose_debug = 1

  antispam_backend = dspam
  antispam_signature = X-DSPAM-Signature
  antispam_signature_missing = error

  antispam_trash = Trash
  antispam_spam = Junk

  antispam_dspam_binary = /usr/bin/dspam
  antispam_dspam_args = --client;--user=%u;--source=error
}

当使用Thunderbird手动将消息移动到垃圾文件夹时，会发生以下情况：

Mar 25 13:24:22 mail imap: antispam: mailbox_is_unsure(Junk): 0
Mar 25 13:24:22 mail imap: antispam: mailbox_is_trash(INBOX): 0
Mar 25 13:24:22 mail imap: antispam: mailbox_is_trash(Junk): 0
Mar 25 13:24:22 mail imap: antispam: mail copy: from trash: 0, to trash: 0
Mar 25 13:24:22 mail imap: antispam: mailbox_is_spam(INBOX): 0
Mar 25 13:24:22 mail imap: antispam: mailbox_is_spam(Junk): 0
Mar 25 13:24:22 mail imap: antispam: mailbox_is_unsure(INBOX): 0
Mar 25 13:24:22 mail imap: antispam: mail copy: src spam: 0, dst spam: 0, src unsure: 0

Mar 25 13:24:31 mail imap: antispam: plugin initialising (2.0-notgit)
Mar 25 13:24:31 mail imap: antispam: verbose debug enabled
Mar 25 13:24:31 mail imap: antispam: "Junk" is exact match spam folder
Mar 25 13:24:31 mail imap: antispam: no unsure folders
Mar 25 13:24:31 mail imap: antispam: "Trash" is exact match trash folder
Mar 25 13:24:31 mail imap: antispam: dspam binary set to /usr/bin/dspam
Mar 25 13:24:31 mail imap: antispam: dspam extra arg --client
Mar 25 13:24:31 mail imap: antispam: dspam extra arg --user=vmail
Mar 25 13:24:31 mail imap: antispam: dspam extra arg --source=error
Mar 25 13:24:31 mail imap: antispam: signature header line is "X-DSPAM-Signature"

但是，与dspam_stats的检查并不意味着已经完成了任何培训。

谢谢你的帮助，拉尔夫

Answer 1

好的，我的装置有两个错误的配置。

第一

我的虚拟用户收件箱位于

/var/mail/vhosts/<domain>/<username>

而不是

/var/mail/vhosts/<domain>/<username>/.INBOX

垃圾文件夹的位置是

/var/mail/vhosts/<domain>/<username>/.Junk

但是(或为此) IMAP名称空间收件箱指向

/var/mail/vhosts/<domain>/<username>/.INBOX

我的配置必须是

antispam_spam = INBOX/Junk

第二个错误实际上与问题无关，但无论如何，我会贴出答案：

dspam命令参数是--user <username>而不是--user=<username> (等号是错误的)，因此配置必须是：

antispam_dspam_args = --client;--source=error;--user;%u

而不是

antispam_dspam_args = --client;--user=%u;--source=error
