Question

我的应用程序在aws EC2上发送电子邮件非常好，突然它开始抛出异常

javax.mail.MessagingException'.
javax.mail.AuthenticationFailedException: 535 5.7.8 Error: authentication failed: authentication failure

这是我的电子邮件设置

mail.smtp.auth=true
mail.smtp.starttls.enable=true
mail.smtp.host=smtp.mydomain.in
mail.smtp.port = 587

我也试过了port 25，但问题仍然存在。

Answer 1

根据您的设置，您需要StartTLS。它的默认端口是587，这很好;把它改成25肯定会打破它。

您的错误消息指出authentication failed，因此我怀疑您要么不提供凭据，要么提供错误的凭据。

无法从AWS发送电子邮件
