今天早上，为了更正安全证书中名称不匹配的问题，我遵循了如何修复邮件服务器SSL？中的建议步骤。，但是现在，当尝试从客户端（在这种情况下，客户端是Windows Mail）发送电子邮件时，我收到以下错误消息。
拒绝的电子邮件地址为“ email@gmail.com”。主题“这是一个测试。'，帐户：'mail.domain.com'，服务器：'mail.domain.com'，协议：SMTP，服务器响应：'554 5.7.1：中继访问被拒绝'，端口：25，安全（SSL）：否，服务器错误：554，错误号：0x800CCC79
编辑：我仍然可以从该帐户检索电子邮件，并且将电子邮件发送到同一域的其他帐户。我只是无法向我们域外的收件人发送电子邮件。
我尝试完全禁用TLS，但没有骰子，但仍然遇到相同的错误。
当我检查文件时mail.log，我看到以下内容。
