grails mail not working - email

grails project. i use email plugin and getting an exception when try call method 'sendMail'
error:
Caused by: org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.NoSuchProviderException: Unable to locate provider for protocol: smtp. Failed messages: javax.mail.NoSuchProviderException: Unable to locate provider for protocol: smtp; message exceptions (1) are:

config.groovy
grails {
mail {
host = "smtp.gmail.com"
port = 465
username = "mymail#gmail.com"
password = "mypass"
props = ["mail.smtp.auth":"true",
//"mail.smtp.port":"465",
//"mail.debug":"true",
"mail.smtp.socketFactory.port":"465",
"mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
"mail.smtp.socketFactory.fallback":"false"]
}
}
example of sending
sendMail {
to "fred#gmail.com"
subject "Hello Fred"
body 'How are you?'
}
what am I doing wrong?
solution

The error say Unable to locate provider for protocol: smtp. It seems you're missing some dependencies for the smtp protocol, which seems very odd, apparently you're missing javamail (?). Because the code seems good to me.

Have you tried to remove
"mail.smtp.port":"465",
"mail.debug":"true",
from your config? This is the only difference I see between your code and the official example.
Update: as GalmWing already stated, it seems to be a problem with your java.mail jar file. Please check this solution: Using Java to send emails on gmail account . It sounds to me like you have the same problem. Which java-version do you use?

add to config.groovy
grails {
mail {
host = "smtp.gmail.com"
port = 465
username = "email"
password = "pwd"
props = ["mail.smtp.auth":"true",
"mail.smtp.socketFactory.port":"465",
"mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
"mail.smtp.socketFactory.fallback":"false"]
}
}
use this code to send mails
def sendEmail(){
mailService.sendMail {
to "email","**email**"
from "email"
subject "Hi"
body 'Hi'
}
}
also dont forget to inject mailservice in your class
def mailService
this will inject the service to your class
and this configuration will be sufficient to send mails

Liferay 7 MailService.sendMail from a custom portlet doesn't work only on HOST SERVER

I have a strange problem with a custom portlet on Liferay 7 to solve:
MailService.sendMail is working from MY COMPUTER with google smtp and a personal account: this means that the code is working...
On my HOST SERVER sending emails with the final-smtp works correctly: I tried both root and liferay user with telnet final-smtp port.
On the Liferay server on HOST SERVER, send e-mails works correctly: if I forget the password, Liferay send me the e-mail.
But ... if I try to send email with my portlet from Liferay on HOST SERVER it doesn't work without any error. I'm using Liferay MailService.sendMail. I post the code but it works (on MY COMPUTER).
I get the service in this way:
#Reference(unbind = "-")
protected void setMailService(MailService mailService) {
_mailService = mailService;
}
And the calling code is in the following:
InternetAddress fromAddress = null;
String newsletterPrefix = null;
InternetAddress toAddress = null;
try {
String smtpUser = PropsUtil.get(
"newsletter.send.mail.smtp.user");
String smtpToUser = PropsUtil.get(
"newsletter.send.mail.smtp.to.user");
if (Validator.isNotNull(smtpUser)) {
fromAddress = new InternetAddress(smtpUser);
}
if (Validator.isNotNull(smtpToUser)) {
toAddress = new InternetAddress(smtpToUser);
}
}
catch (Exception e) {
_log.error(e, e);
result = false;
}
MailMessage mailMessage = new MailMessage(
fromAddress, toAddress, subject, body, true);
mailMessage.setBCC(addressList);
_mailService.sendEmail(mailMessage);
There could be several reasons behind this, some not even code related.
I see you are using this code for a newsletter, which suggests you are using a smtp service that is meant for this.
It could be that your server is in fact sending the email, with success, but the smtp server is simply blocking, rejecting or marking to resend later. Moreover, that server might be configured to not send an error message, or sending an error message in the form of a successful delivery, but the data contains the error.
I would start checking you mail server configuration, and the accounts permissions, then its logs.
Also, you might consider using plugins for mass mail delivery, like this one: https://www.e-systems.tech/blog/-/blogs/connecting-liferay-to-mailgun
Few things you can do to debug this problem:
Make sure you are deploying the intended code on HOST machine. (Silly suggestion, but many times this is the problem.)
Try to set following package's Log level to ALL/DEBUG to see if it shows any problem in logs.com.liferay.mail.service

Getting "Client was not authenticated to send anonymous mail during MAIL FROM" error from Exchange SMTP using Rust lettre library

I am writing a Rust application that will send email through an Exchange server with SMTP functionality enabled. According to Microsoft's webpage, the settings that are required are:
Server address smtp.office365.com
Port 587
StartTLS Enabled
Credentials for mail account login
These are corroborated by the POP/IMAP settings of the webmail service.
Here is my code (with some censoring):
extern crate lettre;
use self::lettre::email::EmailBuilder;
use self::lettre::transport::smtp::{SecurityLevel, SmtpTransportBuilder, SUBMISSION_PORT};
use self::lettre::transport::smtp::authentication::Mechanism;
use self::lettre::transport::EmailTransport;
pub fn send_mail() {
let email = EmailBuilder::new()
.from("my email")
.to("destination email")
.body("testing")
.subject("testing")
.build()
.unwrap();
// Connect to SMTP server
let mut transport = SmtpTransportBuilder::new(("smtp.office365.com", SUBMISSION_PORT))
.expect("Failed to create email transport")
.encrypt()
.smtp_utf8(true)
.credentials("my email", "my password")
.authentication_mechanism(Mechanism::Login)
.build();
println!("Mail transport built");
println!("{:?}", transport.send(email.clone()));
}
When I compile and run the code,it gives me this error:
Err(Permanent(Response { code: Code { severity:
PermanentNegativeCompletion, category: Unspecified3, detail: 0 },
message: ["5.7.57 SMTP; Client was not authenticated to send anonymous
mail during MAIL FROM [SYXPR01CA0106.ausprd01.prod.outlook.com]"] }))
Why is this happening?
The closest I've come in my research is an issue on GitHub in relation to the lettre library not supporting the Login authentication mechanism (which Office 365 uses); however, the codebase was updated to support Login and I am using the master branch directly from GitHub so theoretically my application should support the Login mechanism.
Edit: Forgot to mention that I attempted an EHLO to the server, but it returned a (Client:(Connection closed)) error.
I used telnet and openssl to try connecting directly to my SMTP server, where I found that AUTH LOGIN requires 3 commands; one to send the AUTH LOGIN code, one to send the username and another to send the password. I found that the lettre library implements all its AUTH commands as single commands, so this wasn't working with the server. I downloaded the source code for the library, changed the send function to do the three separate commands, recompiled my code and everything worked fine :)
My addition to the lettre code:
if (accepted_mechanisms[0] == Mechanism::Login) &&
(accepted_mechanisms.capacity() == 1) {
try_smtp!(self.client.command("AUTH LOGIN"), self);
try_smtp!(self.client.command(base64::encode_config(
&username.as_bytes(),
base64::STANDARD).as_str()), self);
try_smtp!(self.client.command(base64::encode_config(
&password.as_bytes(),
base64::STANDARD).as_str()), self);

Grails Non SSL Email Configuratoin

I want to sent email from grails application. Mail server is HARAKA which does not support ssl. Instead of SSL it uses TLS.
Configuration is:
mail `{`
`host = "mm13.us1.emailsrv.net"`
`port = 2525`
`username = "user"`
`password = "pass****"`
`props` = `[`
`"mail.smtp.auth":"true",`
`"mail.smtp.port":"2525",`
`"mail.smtp.socketFactory.fallback":"false",`
`"mail.smtp.starttls.enable": "true"`
`]`
`}`
Facing Error:
Problem sending email Mail server connection failed; nested exception is javax.mail.MessagingException: Could not convert socket to TLS;

Sending a mail with Sendgrid from a Grails 2.0 application on Heroku

I'm trying to send emails from my Grails 2.0 app via Sendgrid on Heroku but I can't find the right configuration. I keep getting "Connection refused" exceptions:

The latest configuration I tried is the following:
grails {
mail {
host = "smtp.sendgrid.net"
port = 587
username = System.env.SENDGRID_USERNAME
password = System.env.SENDGRID_PASSWORD
props = [
"mail.smtp.protocol":"smtps",
"mail.smtp.channel":"plain",
"mail.smtp.auth":"true",
"mail.debug":"true"
]
}
}
It looks like you might have a firewall or ISP blocking port 587. Try this: http://support.sendgrid.com/entries/131119-help-smtp-port-25-is-being-blocked

Actually, the problem came from my Grails configuration. For some reason, my mail config was reset at some point and what I had in Config.groovy was not used. So the app tried to send emails via localhost and that didn't work. I found a workaround to this problem but I don't understand yet why it works.

How do you fix 550 must be authenticated sending Mail using Grails?

I'm using Grails Mail plugin and trying to send email and keep getting:
Error 500: Executing action [sendInvite] of controller
[RegisterController] caused exception: Failed messages:
javax.mail.SendFailedException: Invalid Addresses; nested exception
is: com.sun.mail.smtp.SMTPAddressFailedException: 550 must be
authenticated
I'm properly following the instructions at: http://www.grails.org/Mail+plugin
The mail server is returning an error when you try to send out the mail. 550 is a generic SMTP failure code; in this case it looks like you are missing a username and password. Some SMTP servers to not require authentication but most do, especially if they're publicly available on the internet. It's also possible that your SMTP server requires an SSL connection and you're connecting with an unsecured socket.
The example config for gmail shows how to set all the mail server authentication options in Config.groovy:
grails {
mail {
host = "smtp.gmail.com"
port = 465
username = "youracount#gmail.com"
password = "yourpassword"
props = ["mail.smtp.auth":"true",
"mail.smtp.socketFactory.port":"465",
"mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
"mail.smtp.socketFactory.fallback":"false"]
}
}
Add "mail.debug": "true" to props to turn on JavaMail debugging to get a better picture of what is happening before the failure.
In my case the 550 error was caused by me having accidentally selected and IMAP account as the default account but sending emails from my Outlook Connector Account (which has no authentication settings to make).
I changed the Outlook Connector Account to default. Resent the emails and no errors.
So check that the correct email account is set up as the default also
