Web服务器的SMTP错误
[英]SMTP errors from web server
问题描述
I am having issues with SMTP from one of my web servers. 
我的一台Web服务器上的SMTP出现问题。 I've verified firewall connectivity over port25 to the SMTP relay and the exchange servers is good to go. 我已经验证了通过port25到SMTP中继的防火墙连接性，并且交换服务器可以使用。 I can hit the SMTP relays and exchange server from my web server via telnet. 我可以通过telnet从Web服务器访问SMTP中继和交换服务器。 Whenever I drop a mail in Pickup it sits in the queue. 每当我在“代答”中放入邮件时，它就会排在队列中。
In Event Viewer I get: Message delivery to the host 'IPADDDRESS' failed while delivering to the remote domain 'MYDOMAIN' for the following reason: The connection was dropped by the remote host. 在事件查看器中，我得到：消息传递到主机“ IPADDDRESS”失败，而传递到远程域“ MYDOMAIN”的原因如下：远程主机断开了连接。
I checked SMTPDiag and it comes back: Error: Expecting "220". 我检查了SMTPDiag，它又回来了：错误：预期为“ 220”。 Server is not accepting connections. 服务器不接受连接。 Failed to submit mail to "server.domain.com" 无法将邮件提交到“ server.domain.com”
I checked and my connection control is set to allow and the domains are listed in SMTP.. I am losing my mind trying to figure out why mail is failing at this point.. 我检查了一下，并将连接控制设置为允许，并且域在SMTP中列出了。我迷失了方向，试图弄清为什么邮件在此时失败。

Are you hitting a rate limit or is your outbound ip on a blacklist? 您是要达到速率限制还是出站IP列入黑名单？ Try the blacklist search here: https://mxtoolbox.com/supertoolmobile.aspx 在此处尝试黑名单搜索： https ： //mxtoolbox.com/supertoolmobile.aspx
