dovecot SquirrelMail w / Fedora连接上的sendmail在发送时被拒绝

我们使用Fedora 25和sendmail-8.15.2-8.fc25.x86_64，同时通过SquirrelMail发送消息需要相当长的一段时间。 这些日志显示：

delay=00:00:15, xdelay=00:00:00, mailer=relay, pri=46987, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1] 

我试过这个build议 ：

 # SMTP daemon options O DaemonPortOptions=Family=inet, Name=MTA-v4, Port=smtp, Addr=XX.XX.XX.XX O DaemonPortOptions=Family=inet, Name=MTA-v4, Port=smtp, Addr=127.0.0.1 O DaemonPortOptions=Family=inet, Name=MSP-v4, Port=submission, M=Ea, Addr=127.0.0.1 

和：

 cat /etc/hosts.allow ALL : 127.0.0.1 

Firewalld也可以：

• CentOS 6.x电子邮件路由奇怪
• 发送群发邮件到单个服务器
• sendmail花了很多时间发送电子邮件
• Mimedefang将spamassassin分数logging到邮件日志
• 身份validation成功，但发送仍然失败

 firewall-cmd --permanent --list-all [...] services: samba imaps pop3s http ssh nfs samba-client smtp dhcpv6-client mysql cockpit https vnc-server postgresql ipp-client mdns ipp dns rich rules: rule family="ipv4" source address="218.65.30.108" reject rule family="ipv4" source address="72.9.101.182" reject 

还有什么要检查？ 邮件最终会出去。 花了差不多一分钟。

编辑：使用这里的build议 ，我至less能够得到邮件出去。 现在看来SpamAssassin正在放慢速度，因为Pyzor是罪魁祸首。
