So make sure you get the TLS port. port # This is what you use in the “username” field when # you login. Typically # you login. Typically this is the same as your email # address, but this isnt always the case . username # This is what you use in the “password” field when # you login. This value is CLEAR TEXT, so keep # you login. This value is CLEAR TEXT, so keep this # properties file safe. password # This is the email address you want for the # emails FROM field. Enter the value using # the format shown below. Typically # the format shown below. Typically this is # just your email address for the account. fromFIRSTNAME LASTNAME ADDRESS EMAIL .COM # This is the email address you want for the # emails REPLY_TO field. Enter the value using # the format shown below. Typically # the format shown below. Typically this is # just your email address for the account. Also the account. Also # typically this is the same as from above. # But be warned, if an emails FROM and REPLY_TO # are different, thats may be flagged as spam # and never be delivered. So keep from and # reply the same for initial testing replyFIRSTNAME LASTNAME ADDRESS EMAIL .COM # This is the email address you want to send # the email to. For testing, its a good idea # to send it to yourself first. toFIRSTNAME LASTNAME ADDRESS EMAIL .COM 现在您有了属性文件接下来让我们看一下代码。 码 这是一个JUnit测试演示了如何使用Java Mail通过具有TLS连接的SMTP服务器发送电子邮件。 清单2显示了代码。 注意对于初始测试请始终检查您的SPAM文件夹。 可以始终添加一条规则以将其传送到您的INBOX。 清单2 – Java Mail示例 package org.thoth.email.via.tls; import java.net.InetAddress; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Properties; import javax.mail.Authenticator; import javax.mail.Message; import javax.mail.PasswordAuthentication; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeBodyPart; import javax.mail.internet.MimeMessage; import javax.mail.internet.MimeMultipart; import org.junit.jupiter.api.BeforeEach; import org.junit.jupiter.api.Test; public class TlsTest { public TlsTest() { } String now, hostname; protected String now, hostname; protected Properties outlook; BeforeEach public void setUp() throws Exception { now new SimpleDateFormat( MM-dd-yyyy hh:mm:ss a ).format( new Date()); hostname InetAddress.getLocalHost().getHostName(); outlook new Properties(); outlook.load( this .getClass().getResourceAsStream( /smtp-tls-outlook.properties )); } Test public void a_test() throws Exception { // Create MimeMultipart MimeMultipart content new MimeMultipart( related ); // html part { MimeBodyPart textPart new MimeBodyPart(); textPart.setText( htmlbody pTime: now /p pFrom: hostname /p /body/html , UTF8 , html ); content.addBodyPart(textPart); } // properties Properties props new Properties(); { props.setProperty( mail.smtp.auth , true ); props.setProperty( mail.smtp.host , outlook.getProperty( host )); props.setProperty( mail.smtp.port , outlook.getProperty( port )); props.setProperty( mail.smtp.starttls.enable , true ); } Session smtp null ; { smtp Session.getInstance(props, new Authenticator() { Override protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication( outlook.getProperty( username ) , outlook.getProperty( password ) ); } }); smtp.setDebug( true ); smtp.setDebugOut(System.out); } MimeMessage m new MimeMessage(smtp); { m.setRecipient(Message.RecipientType.TO, new InternetAddress(outlook.getProperty( to ))); m.setSubject( thoth-email TLS test now); InternetAddress from null ; { from new InternetAddress(outlook.getProperty( from )); from.setPersonal( Thoth Email ); m.setFrom(from); } InternetAddress reply null ; { reply new InternetAddress(outlook.getProperty( reply )); m.setReplyTo( new InternetAddress[] {reply}); } m.setContent(content); } Transport.send(m); } } 摘要 发送邮件的代码不是很困难。 成功接收电子邮件而不将其标记为垃圾邮件是另一回事。 但是如果您遵循此示例请使用有效的帐户并且不要过度使用它则应该可以。 该博客显示了如何使用Java Mail通过具有TLS连接的SMTP服务器发送电子邮件。 翻译自: https://www.javacodegeeks.com/2020/02/java-mail-sent-over-tls.html
