my problem started after changed mail_url variable:

process.env.mail_url = 'smtp://postmaster%40sandbox:password@smtp.mailgun.org:587'; 

the error shows syntax error @ 11:19 in file . in email.send

if (meteor.isserver) { meteor.startup(function () {     process.env.mail_url = 'smtp://postmaster%40sandbox:password@smtp.mailgun.org:587'; }); meteor.methods({     sendemail: function (to, from, subject, text) {         check([to, from, subject, text], [string]);         // let other method calls same client start running,         // without waiting email sending complete.         this.unblock();         email.send({             to: to,             from: from,             subject: subject,             text: text         });     }); } 

this example call method in register form:

template.register.events({ 'submit form': function (event) {     event.preventdefault();      var remail = $('[id=registeremail]').val();     var rpassword = $('[id=registerpassword]').val();     var passwordconfirm = $('[id=passwordconfirm]').val();     var rname = $('#registername').val();     var rsurname = $('#registersurname').val();      if (isemail(remail) && arevalidpasswords(rpassword, passwordconfirm)) {           var iduser = accounts.createuser({             email: remail,             password: rpassword,             profile: {                 'name': rname,                 'surname': rsurname             }         }, function (error) {             if (error) {                 window.alert(error.reason);             } else {                 router.go("home");             }         }         );         meteor.call('sendemail',remail,'sentfrom','subject','content');         meteor.settimeout(function(){router.go('dashboard')}, 2000);     }     else         return false;    } }); 

i'm using exact method mentioned in meteor docs , worked before changing smtp.

your from argument has in correct email address format ("******@****.**") in order email sent. right giving "sentfrom" sender address!

have @ the example again:

meteor.call('sendemail',             'alice@example.com',             'bob@example.com',             'hello meteor!',             'this test of email.send.');
