Sending a Mail on Jenkins Pipeline - email

Question

hi I have a simple pipeline job that should send a mail, I configured on Manage jenkins -> Configure System with port 465 and the appropriated SMTP server , when I test the configuration by sending a e-mail , it sends and I can see the test mail on my inbox , but from the pipeline job , it fails:
node {
stage("test") {
def message = "hello there!"
mail bcc: '', body: message, cc: '', from: 'jenkinsuser#mycom.com', replyTo: 'jenkinsuser#mycom.com', subject: "Develop: build generated ", to:'grace#mycom.com'
}
}
Error:
java.net.SocketException: Connection closed by remote host
at sun.security.ssl.SSLSocketImpl.checkWrite(Unknown Source)

at com.sun.mail.smtp.SMTPTransport.sendCommand(SMTPTransport.java:2093)
at com.sun.mail.smtp.SMTPTransport.close(SMTPTransport.java:1184)
Any suggestion how to fix it?

I am using Email Extension plugin in scripted pipeline with no issues. Make sure you properly configured E-mail Notification section in Manage Jenkins > Configure System. Example for gmail:
Jenkins e-mail notifications settings
Plugin usage is described here: here. This is how I call it in Pipeline (I didn't remove variables):
emailext attachmentsPattern: "**/packages/rpm/splitted/${file}",
to: "${to}",
from: "Jenkins",
subject: "[jenkins] ${packageFullName}: part ${part}/${files.size()}",
body: "File received: \'${file}\'\n" +
"From package: \'${packageFullName}\'\n" +
"Package MD5: \'${mainMdFiveSum}\'\n" +
"Jenkins Build: \'${env.BUILD_URL}\'\n"
