我需要使用Play Mailer（https://github.com/playframework/play-mailer）从Play应用程序发送电子邮件。
在我的GMail帐户中，我启用了双因素身份验证，这是公司政策 - 我无法关闭。所以我使用的密码是我生成的特定于应用程序的密码。
我也无法启用“不太安全的应用”（https://support.google.com/accounts/answer/6010255?hl=en）。
我已将此电子邮件和密码值更改为此帖子的通用值。
对于Play Mailer，我在application.conf中有这些参数：
# Mailer
# ~~~~~
play.mailer {
host="smtp.gmail.com"
port=587
ssl=false
tls=true
user="myemail@email.com"
password="mypassword" # This is the application specific generated password
debug=false
mock=false
from="thisemail@email.com"
}
我正在使用此代码发送电子邮件：
/**
* Send mail with the new password.
*
* @param user
* user created
* @throws EmailException
* Exception when sending mail
*/
private void sendPasswordChanged(User user) throws EmailException {
String subject = Messages.get("mail.reset.confirm.subject");
String message = Messages.get("mail.reset.confirm.message");
Mail.Envelop envelop = new Mail.Envelop(subject, message, user.getEmail());
Mail mailer = new Mail(mailerClient);
mailer.sendMail(envelop);
}
在application.conf中设置mock=true时，我可以看到正确创建的电子邮件包含所有正确的值：
[info] play.api.Play - Application started (Dev)
[info] application - mock implementation, send email
[info] application - subject: Account Access Attempted
[info] application - from: thisemail@email.com
[info] application - bodyText: You (or someone else) entered this email address
when trying to change the password. However, this email address is not on our l
ist of registered users, and so the attempted password reset has failed.
null
[info] application - bodyHtml: You (or someone else) entered this email address
when trying to change the password. However, this email address is not on our l
ist of registered users, and so the attempted password reset has failed.<br><br>
--<br>null
[info] application - to: myemail@email.com
但是，当我设置mock=false时，我收到此错误：

我尝试过不同的组合：
port=587
ssl=false
tls=true
和
port=465
ssl=true
tls=false
但是他们都给了我同样的错误。
我无法在工作时在我的Gmail帐户上启用IMAP或POP3 - 政策不允许这样做。
还有另一种方法可以让它发挥作用吗？
