使用 jenkins 发送电子邮件时出错

Question

I'm trying to use email sending in jenkins. I leave default values, click on 'Test configuration' button and get error:

Failed to send out e-mail

javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25; nested exception is: java.net.SocketException: Permission denied: connect

at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1934)

at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:638)

What I missed? It's not working by default?

Answer 1

I configured Jenkins with my gmail account using the settings as given in the image below.

Answer 2

I had similar problem couldn't send email via zoho. The configurations were: SMPT TLS Zoho Configurations I just need to change system admin address in jenkins configurations to the same one in email-notifications.

Here you can find the system admin e-mail: Manage Jenkins -> Configure System -> Jenkins Location -> System Admin e-mail address

Answer 3

I was also struggling with this error. Here is how I resolved it.

1. Google account settings:

Go to Gmail account settings -> Forwarding and POP/IMAP -> IMAP Access -> Enable IMAP (This is to enable both IMAP & SMTP settings)

Check configuration details that are mentioned as:

• Outgoing Mail (SMTP) Server: smtp.gmail.com
• Requires SSL: Yes
• Requires TLS: Yes (if available)
• Requires Authentication: Yes
• Port for SSL: 465
• Port for TLS/STARTTLS: 587

(Rather than going with settings mentioned by anyone, please checkout your account for this info as settings/configurations keep on changing. )

2. Jenkins (2.121.3) settings:

Manage Jenkins -> Configure System -> Scroll down to E-mail Notification tab -> Advanced

• Use SMTP Authentication: checked
• User Name: <your gmail id>
• Password: <your password>
• Use SSL: checked
• SMTP Port: 465
• Reply-To Address: Optional (I left it blank. You can give any email id you want)
• Charset: UTF-8

Enable "Test configuration by sending test e-mail", give test email id and hit "test configuration" button

NOTE:

1. Make sure you are connected to open network (that is not antivirus protected or antivirus may block your emails). I used my phone internet instead of office internet for testing this.
2. I didn't change any McAfee settings for doing this. Just switch your internet to open one.

Answer 4

There is no SMTP server running on localhost or you don't have the permission to connect to it.

Check the configuration of Jenkins.

Answer 5

If anyone is still having issues with emails in Jenkins, a lot has changed since then.

If you have a custom domain name for g-mail and it requires a 2-step authentication to login, for example you@yourcompany.com ,

SMTP server should still be smtp.gmail.com

Default user e-mail suffix should be @yourcompany.com

Because Google no longer allows you to simply use your default e-mail password to login via any outside apps, in this case Jenkins. It is a lot more secure to let Google create a custom password for Jenkins rather than turning off G-Mail's security features to allow Jenkins access to your account.

Create the App Password here: https://security.google.com/settings/security/apppasswords

Use the generated password in Jenkins -> Configure Systems -> E-Mail Configuration

Answer 6

You probably don't have SMTP running on your machine, which is the usual state for Windows or Mac servers.

To test this , use any known mail-server for that, for example - if you have a gmail account, try this:

SMTP server: smtp.gmail.com

Default user e-mail suffix: @something.something

Sender E-mail Address: your-mail@gmail.com

If planning to use the mail-notifications as part of your build-process,
it is best to set the SMTP properly, or maybe move the Jenkins/Hudson server to a machine that supports this.

Answer 7

Check if your provider blocks port 25.

In order to make a proper test

telnet smtp.gmail.com 25

If you receive an answer like this:

telnet: connect to address 74.125.206.108: Connection refused

You should go with smtp authentication as described in harikrishna-pai's answer

Answer 8

I had same issue and managed to resolved by following,

1. Generate Gmail App Password, Gmail App

2. In Jenkins use the app password, Jenkin's Configuration
