在德尔福体育俱乐部会员计划中,我使用俱乐部的BTConnect帐户向会员发送批量电子邮件,该帐户已迁移到Office365。最近,BT提升了身份验证,我将SMTP参数从satNone更改为satDefault和utUseExplicitTLS。如果我从家里运行程序,它按预期工作:

然后关闭它,没问题。 如果我将该计划带到体育俱乐部并在那里运行,我就明白了:

似乎Indy正在发出QUIT而不是第二个EHLO命令,但我找不到原因。我将设置更改为使用satSASL和相关机制,结果相同。它在家里工作得很好,但不是来自俱乐部。有什么办法可以解决这个问题吗?我也在一周前将Indy更新到最新版本。

谢谢

当服务器收到STARTTLS命令并以成功响应回复时,它希望TIdSMTP在发送任何进一步的命令之前启动SSL / TLS握手。在这种情况下,SSL / TLS握手必须失败,您应该收到异常。如果发生异常,TIdSMTPBase.StartTLS()会调用Disconnect()。这是TIdSMTP在成功QUIT命令后发送STARTTLS命令的唯一方式,而不是发送第二个EHLO
