我在程序中使用了简单Java邮件库(http://www.simplejavamail.org),我想设置一个本地名称,该名称应在发送电子邮件时在EHLO中发送。我试图这样做:
Properties props = new Properties();
props.put("mail.smtp.sendpartial", "true");
props.put("mail.smtp.host", "smtp.mail.ru");
props.put("mail.smtp.localhost", "mail.ru");
Mailer mailer = MailerBuilder
.withSMTPServer(server, port, login, password)
.withTransportStrategy(TransportStrategy.SMTPS)
.withSessionTimeout(10 * 1000)
.clearEmailAddressCriteria()
.withProperties(props)
.withDebugLogging(true)
.buildMailer();
正如您在代码中看到的那样,现在我应该在EHLO中有“ mail.ru”,但这没有发生,我一直使用计算机的名称。我在日志中看到以下内容:
DEBUG: getProvider() returning javax.mail.Provider[TRANSPORT,smtps,com.sun.mail.smtp.SMTPSSLTransport,Oracle]
DEBUG SMTP: useEhlo true, useAuth true
DEBUG SMTP: useEhlo true, useAuth true

DEBUG SMTP: Found extension "AUTH", arg "PLAIN LOGIN XOAUTH2"
DEBUG SMTP: Attempt to authenticate using mechanisms: LOGIN PLAIN DIGEST-MD5 NTLM
DEBUG SMTP: AUTH LOGIN command trace suppressed

我在做什么错?如何设置mail.smtp.localhost?
答案 0 :(得分:1)
如果启用了SSL,请尝试mail.smtps.localhost
或mail.smtps.localaddress
。否则,可以使用mail.smtp.localhost
或mail.smtp.localaddress
。
在您使用TransportStrategy.SMTPS
的情况下,这意味着已显式启用SSL,因此mail.smtp.localhost
的普通连接将不起作用。
下面是我的参考[从SMTPTransport类文件粘贴]:
public synchronized String getLocalHost() {
if(this.localHostName == null || this.localHostName.length() <= 0) {
***this.localHostName = this.session.getProperty("mail." + this.name + ".localhost");***
}
if(this.localHostName == null || this.localHostName.length() <= 0) {
***this.localHostName = this.session.getProperty("mail." + this.name + ".localaddress");***
}
InetAddress localHost;
try {
if(this.localHostName == null || this.localHostName.length() <= 0) {
localHost = InetAddress.getLocalHost();
this.localHostName = localHost.getCanonicalHostName();
if(this.localHostName == null) {
this.localHostName = "[" + localHost.getHostAddress() + "]";
}
}
} catch (UnknownHostException var2) {
;
}
if((this.localHostName == null || this.localHostName.length() <= 0) && this.serverSocket != null && this.serverSocket.isBound()) {
localHost = this.serverSocket.getLocalAddress();
this.localHostName = localHost.getCanonicalHostName();
if(this.localHostName == null) {
this.localHostName = "[" + localHost.getHostAddress() + "]";
}
}
return this.localHostName;
}
