-

i send emails using javamail. have class able (few months ago send emails), program stops on transport.connect(emailhost, from, frompassword);

sendmails activity: 

public class sendmails {      final string smtpauth = "true";     final string starttls = "true";     final string emailhost = "smtp.gmail.com";      string fromemail;     string frompassword;     list<string> toemaillist;     string emailsubject;     string emailbody;     string emailport;      properties emailproperties;     session mailsession;     mimemessage emailmessage;      private emailaccount account;     private emailauthenticator authenticator;      public sendmails() {      }      public sendmails(string fromemail, string frompassword,             list<string> toemaillist, string emailsubject, string emailbody,             string emailport) {         this.fromemail = fromemail;         this.frompassword = frompassword;         this.toemaillist = toemaillist;         this.emailsubject = emailsubject;         this.emailbody = emailbody;         this.emailport = emailport;          string[] splited = fromemail.split("@");         log.w("send mails", splited[0] + "+" + splited[1]);         account = new emailaccount(splited[0], frompassword, splited[1]);         authenticator = new emailauthenticator(account);         log.w("sendmails", " " + emailport);         emailproperties = system.getproperties();         emailproperties.put("mail.smtp.port", this.emailport);         emailproperties.put("mail.smtp.auth", smtpauth);         emailproperties.put("mail.smtp.starttls.enable", starttls);     }      public mimemessage createemailmessage() throws addressexception,             messagingexception, unsupportedencodingexception {          mailsession = session.getdefaultinstance(emailproperties, null);         emailmessage = new mimemessage(mailsession);          emailmessage.setfrom(new internetaddress(fromemail, fromemail));         (string toemail : toemaillist) {             log.i("gmail", "toemail: " + toemail);             emailmessage.addrecipient(message.recipienttype.to,                     new internetaddress(toemail));         }          emailmessage.setsubject(emailsubject);         // emailmessage.setcontent(emailbody, "text/html");// html email         emailmessage.settext(emailbody);// text email         log.i("gmail", "email message created.");         return emailmessage;     }      public void sendemail() throws addressexception, messagingexception {         transport transport = mailsession.gettransport("smtp");         log.i("gmail", "all: " + emailhost + " " + fromemail + " "                 + frompassword + " " + emailmessage.tostring()+ " " + fromemail.split("@")[0].tostring());          string = fromemail.split("@")[0].tostring();         log.i("gmail", "from: " + from);          try {             transport.connect(emailhost, from, frompassword);         } catch (exception e) {             e.printstacktrace();         }         log.i("gmail", "allrecipients: " + emailmessage.getallrecipients());         transport.sendmessage(emailmessage, emailmessage.getallrecipients());         transport.close();         log.i("gmail", "email sent successfully.");     }  }

the last log log.i("gmail", "from: " + from); , log.i("gmail", "allrecipients: " + emailmessage.getallrecipients()); never shown ...also no exceptions thrown ..

thanks lot :)
