之前用163邮箱发邮件时明明是成功的,但是使用中国移动自己的邮箱时,无论如何在linux服务器中都发送不成功,一开始报如下错误:
javax.mail.MessagingException: Unknown SMTP host: mail.chinamobilesz.com at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1959) ~ [mail-1.4.7.jar:1.4.7] at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:65 4) ~[mail-1.4.7.jar:1.4.7] at javax.mail.Service.connect(Service.java:317) ~[mail-1.4.7.jar:1.4.7] at javax.mail.Service.connect(Service.java:176) ~[mail-1.4.7.jar:1.4.7] at javax.mail.Service.connect(Service.java:125) ~[mail-1.4.7.jar:1.4.7] at javax.mail.Transport.send0(Transport.java:194) ~[mail-1.4.7.jar:1.4.7 ] at javax.mail.Transport.send(Transport.java:124) ~[mail-1.4.7.jar:1.4.7] at com.cmsz.processOm.service.impl.EmailSendServiceImpl.sendEmail(EmailS endServiceImpl.java:107) ~[EmailSendServiceImpl.class:na] at com.cmsz.processOm.controller.WorkOrderController$SendEmail.isSendEma il(WorkOrderController.java:555) [WorkOrderController$SendEmail.class:na] at com.cmsz.processOm.controller.WorkOrderController$SendEmail.run(WorkO rderController.java:524) [WorkOrderController$SendEmail.class:na] at java.lang.Thread.run(Thread.java:745) [na:1.7.0.11] ......
在linux中telnet mail.chinamobilesz.com 25也不通,但是直接把mail.chinamobilesz.com换成ip就可以了,在网上查找资料并参考其他文章后,设置了主机名和ip的映射后终于telnet成功连接:
参考:http://blog.csdn.net/mchdba/article/details/49339715
但是尽管telnet成功连接了,启动项目后发送邮件依然报错,只不过换了一个错误而已:
javax.mail.MessagingException: Could not connect to SMTP host: mail.chinamobilesz.com, port: 25 at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1961) ~[mail-1.4.7.jar:1.4.7] at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:654) ~[mail-1.4.7.jar:1.4.7] at javax.mail.Service.connect(Service.java:317) ~[mail-1.4.7.jar:1.4.7] at javax.mail.Service.connect(Service.java:176) ~[mail-1.4.7.jar:1.4.7] at javax.mail.Service.connect(Service.java:125) ~[mail-1.4.7.jar:1.4.7] at javax.mail.Transport.send0(Transport.java:194) ~[mail-1.4.7.jar:1.4.7] at javax.mail.Transport.send(Transport.java:124) ~[mail-1.4.7.jar:1.4.7] at com.cmsz.processOm.service.impl.EmailSendServiceImpl.sendEmail(EmailSendServiceImpl.java:107) ~[EmailSendServiceImpl.class:na] at com.cmsz.processOm.controller.WorkOrderController$SendEmail.isSendEmail(WorkOrderController.java:555) [WorkOrderController$SendEmail.class:na] at com.cmsz.processOm.controller.WorkOrderController$SendEmail.run(WorkOrderController.java:524) [WorkOrderController$SendEmail.class:na] at java.lang.Thread.run(Thread.java:745) [na:1.7.0.11] ......
查找很多资料还是没能解决问题,不明白明明可以telnet的,为什么到了程序中就连接不上。如此折腾了好久,最终由组长出马解决了问题,我也才终于知道了原因。竟然是项目中如下代码导致:
// SSL加密 MailSSLSocketFactory sf = null; try { sf = new MailSSLSocketFactory(); // 设置信任所有的主机 sf.setTrustAllHosts(true); proerties.put("mail.smtp.ssl.enable", "true"); proerties.put("mail.smtp.ssl.socketFactory", sf); } catch (GeneralSecurityException e) { e.printStackTrace(); }
使用了这一段代码后,连接的是465端口,不是25,但是实际上移动提供给我的邮箱没有开465这个端口,因此便造成不论是465还是25端口都连接不上,于是去掉这段代码后,启动项目再次发送邮件便成功了。
