Sending Emails from java using specific Gmail accont -

i have email hosting account company gmail , trying send emails account in java facing following error:

 javax.mail.authenticationfailedexception: 534-5.7.14 <https://accounts.google.com/signin/continue?sarp=1&scc=1&plt=akgnsbsf 534-5.7.14 i7zvgrt2ia4he_atvycpueorgulhg4yvg6hw_jgdagbyukbfjysvdr_xvkzlzzqp88f-un 534-5.7.14 aogu0un-ubur91zw7jsbzeq8ojr6fejfqcpsvkpv9glaupy3ee-puk3y6enabfea8dgdlu 534-5.7.14 fndqwlg_r1i5-veywj8qe73r833f8phwfurancjtkypjqogqo-vrbg6omrzhsp3i-8wphr 534-5.7.14 ajvaiqquhwnrurmkjyk6rkajnyaia> please log in via web browser , 534-5.7.14 try again. 534-5.7.14  learn more @ 534 5.7.14  https://support.google.com/mail/answer/78754 w77sm17182835wmw.10 - gsmtp 

and here properties using in code:

    final string username = "email@mycompnay.com";     final string password = "********";       final string host = "smtp.gmail.com";     final string port = "587";      // creating properties object     properties props = new properties();     // defining properties     props.put("mail.smtp.host", host);     props.put("mail.transport.protocol", "smtp");     props.put("mail.smtp.auth", "true");     props.put("mail.smtp.starttls.enable", "true");      props.put("mail.user", username);     props.put("mail.password", password);     props.put("mail.port", port);      // authorized session object.     session mailsession = session.getinstance(props, new javax.mail.authenticator() {         @override         protected passwordauthentication getpasswordauthentication() {             return new passwordauthentication(username, password);         }     }); 

so clear, email (myemail@mycompany.com) , mycompany.com emails hosted on gmail. , if replace email gmail email (email@gmail.com) works properly, problem here , how solve it.

i think problem properties mail.smtp.port, mail.smtp.socketfactory.port

please specify if not , change port number should work fine you.

try set of properties... code must work (a working code added running project)

            v_objproperties = new properties();             v_objproperties.put("mail.smtp.host","smtp.gmail.com");               v_objproperties.put("mail.smtp.auth", "true");               v_objproperties.put("mail.debug", "false");               v_objproperties.put("mail.smtp.port",25);               v_objproperties.put("mail.smtp.socketfactory.port",25);               v_objproperties.put("mail.smtp.starttls.enable", "true");             v_objproperties.put("mail.transport.protocol", "smtp");             v_objsession = session.getinstance(v_objproperties, new authenticator() {                 @override                 protected passwordauthentication getpasswordauthentication() {                     return new passwordauthentication("abc@abc.com", "*********");                 }             });
