Sending mail is a common feature for Jenkins. After a large number of user practice feedback, only one way is recommended, that is, using the third-party STMP service to send the email.
Do not try to install Sendmail or other Mail server software on your Cloud Server for sending mail, because it is very difficulty in maintenance.
Follow is the sample using SendGrid's SMTP Service to configure sending mail for Jenkins:
Install the Jenkins plugin Email Extension (opens new window)
Log in SendGrid console, prepare your SMTP settings like the follow sample
SMTP host: smtp.sendgrid.net SMTP port: 25 or 587 for unencrypted/TLS email, 465 for SSL-encrypted email SMTP Authentication: must be checked SMTP Encryption: must SSL SMTP username: websoft9smpt SMTP password: #fdfwwBJ8f
Log in Jenkins Console, open 【Manage Jenkins】>【Configure System】, set you SMTP
More SMTP Service(Gmail, Hotmail, QQ mail, Yahoo mail, SendGrid and so on) settings or Issues with SMTP, please refer to Websoft9's SMTP Guide (opens new window)
