Dovecot Replication 没有通知

我在 Ubuntu 18.04.1 上安装了 dovecot v2.2.33.2。我已按照通常为 HA 服务器配置的方式配置了 Dovecot 复制器，但出于某种原因，它不会将进入 mx1 的新电子邮件同步到 mx2。如果我在 mx1 上打开电子邮件并阅读，它会同步到 mx2。或者如果我删除它，情况也一样。

如果我在 mx2 上写了一封新电子邮件并发送，它会立即同步到 mx1。

就像 mx1 没有向 mx2 发送新电子邮件的新通知，但是一旦我打开电子邮件，同步就可以正常工作。

我已经设置了几次复制，从来没有遇到过这个问题，不确定问题出在哪里。

mx1 和 2 上的配置相同，当然除了各自的 IP 指向对方之外。

文件如下dovecot.conf：

listen = *,[::]
protocols = imap pop3
auth_mechanisms = plain login
disable_plaintext_auth = no
log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_privileged_group = vmail
postmaster_address = [email protected]
ssl_cert = </etc/postfix/smtpd.cert
ssl_key = </etc/postfix/smtpd.key
ssl_protocols =  !SSLv3
mail_max_userip_connections = 100
passdb {
  args = /etc/dovecot/dovecot-sql.conf
  driver = sql
}
userdb {
  driver = prefetch
}
userdb {
  args = /etc/dovecot/dovecot-sql.conf
  driver = sql
}
plugin {
  quota = dict:user::file:/var/vmail/%d/%n/.quotausage
  sieve=/var/vmail/%d/%n/.sieve
  sieve_max_redirects = 25
}
service auth {
  unix_listener /var/spool/postfix/private/auth {
    group = postfix
    mode = 0660
    user = postfix
  }
  unix_listener auth-userdb {
    group = vmail
    mode = 0600
    user = vmail
  }
  user = root
}
service lmtp {
  unix_listener /var/spool/postfix/private/dovecot-lmtp {
   group = postfix
   mode = 0600
   user = postfix
  }
}
service imap-login {
  client_limit = 1000
  process_limit = 512
}
protocol imap {
  mail_plugins = quota imap_quota
}
protocol pop3 {
  pop3_uidl_format = %08Xu%08Xv
  mail_plugins = quota
}
protocol lda {
postmaster_address = [email protected]
  mail_plugins = sieve quota
}
protocol lmtp {
postmaster_address = [email protected]
  mail_plugins = quota sieve
}
mail_plugins = $mail_plugins quota

# Enable the replication plugin globally
mail_plugins = $mail_plugins notify replication quota

# Both the client and the server need to have a shared secret
doveadm_password = pass_word

# configure how many dsyncs can be run in parallel (10 by default)
replication_max_conns = 10

service aggregator {
        fifo_listener replication-notify-fifo {
                user = vmail
                mode = 0666
        }

        unix_listener replication-notify {
                user = vmail
                mode = 0666
        }
}

service replicator {
        unix_listener replicator-doveadm {
                mode = 0666
        }
}

service doveadm {
        user = vmail
        inet_listener {
                port = 4711
        }
}

service config {
        unix_listener config {
                user = vmail
        }
}

# use tcp:ip as the dsync target
plugin {
        replication_full_sync_interval = 1 hours
        mail_replica = tcp:0.0.0.0:4711
}

protocol imap {
        mail_plugins = quota imap_quota notify replication
}

此外，如果我运行doveadm replicator replicate '*'强制复制，它会立即将待处理的电子邮件发送到 mx2。但如果没有它，它就不会。在我的测试期间，我让它自动向 mx2 发送一次，大约需要 20 分钟。

从那时起，它就没再自动执行过。状态显示上次同步时间一直在增加，除非我强制执行或打开电子邮件，否则它不会回到零。

您忘记了协议块中的插件：

protocol imap {
  mail_plugins = notify replication quota imap_quota
}
protocol pop3 {
  pop3_uidl_format = %08Xu%08Xv
  mail_plugins = notify replication quota
}

添加它们后，您的邮箱发生变化后，它会显示在复制状态中：

# doveadm replicator status '*'
username               priority fast sync full sync success sync failed
[email protected]           none     00:00:03  00:33:57  00:00:03     -
