Configuring email for notifications

To make it easy for users to respond quickly to activity on GitHub Enterprise Server, you can configure your GitHub Enterprise Server instance to send email notifications for issue, pull request, and commit comments.

Configuring SMTP for your enterprise

  1. Em uma conta administrativa no GitHub Enterprise Server, no canto superior direito de qualquer página, clique em .

    Captura de tela do ícone de foguete para acesso � s configurações de administração do site

  4. Na barra lateral esquerda, clique em Email. Guia Email

  5. Select Enable email. This will enable both outbound and inbound email, however for inbound email to work you will also need to configure your DNS settings as described below in "Configuring DNS and firewall settings to allow incoming emails." Enable outbound email

  6. Type the settings for your SMTP server.

    • In the Server address field, type the address of your SMTP server.
    • In the Port field, type the port that your SMTP server uses to send email.
    • In the Domain field, type the domain name that your SMTP server will send with a HELO response, if any.
    • Select the Authentication dropdown, and choose the type of encryption used by your SMTP server.
    • In the No-reply email address field, type the email address to use in the From and To fields for all notification emails.
  7. If you want to discard all incoming emails that are addressed to the no-reply email address, select Discard email addressed to the no-reply email address. Checkbox to discard emails addressed to the no-reply email address

  8. Under Support, choose a type of link to offer additional support to your users.

    • Email: An internal email address.
    • URL: A link to an internal support site. You must include either http:// or https://. Support email or URL
  9. Test email delivery.

Testing email delivery

  1. At the top of the Email section, click Test email settings. Test email settings

  2. In the Send test email to field, type an address to send the test email to. Test email address

  3. Click Send test email. Send test email

    Tip: If SMTP errors occur while sending a test email—such as an immediate delivery failure or an outgoing mail configuration error—you will see them in the Test email settings dialog box.

  4. If the test email fails, troubleshoot your email settings.

  5. When the test email succeeds, at the bottom of the page, click Save settings. Save settings button

  6. Aguarde a conclusão da execução de suas configurações.

Configuring DNS and firewall settings to allow incoming emails

If you want to allow email replies to notifications, you must configure your DNS settings.

  1. Ensure that port 25 on the instance is accessible to your SMTP server.
  2. Create an A record that points to reply.[hostname]. Depending on your DNS provider and instance host configuration, you may be able to instead create a single A record that points to *.[hostname].
  3. Create an MX record that points to reply.[hostname] so that emails to that domain are routed to the instance.
  4. Create an MX record that points noreply.[hostname] to [hostname] so that replies to the cc address in notification emails are routed to the instance. For more information, see "Configuring notifications."

Troubleshooting email delivery

Create a Support Bundle

If you cannot determine what is wrong from the displayed error message, you can download a support bundle containing the entire SMTP conversation between your mail server and GitHub Enterprise Server. Once you've downloaded and extracted the bundle, check the entries in enterprise-manage-logs/unicorn.log for the entire SMTP conversation log and any related errors.

The unicorn log should show a transaction similar to the following:

This is a test email generated from https://10.0.0.68/setup/settings
Connection opened: smtp.yourdomain.com:587
-> "220 smtp.yourdomain.com ESMTP nt3sm2942435pbc.14\r\n"
<- "EHLO yourdomain.com\r\n"
-> "250-smtp.yourdomain.com at your service, [1.2.3.4]\r\n"
-> "250-SIZE 35882577\r\n"
-> "250-8BITMIME\r\n"
-> "250-STARTTLS\r\n"
-> "250-ENHANCEDSTATUSCODES\r\n"
-> "250 PIPELINING\r\n"
<- "STARTTLS\r\n"
-> "220 2.0.0 Ready to start TLS\r\n"
TLS connection started
<- "EHLO yourdomain.com\r\n"
-> "250-smtp.yourdomain.com at your service, [1.2.3.4]\r\n"
-> "250-SIZE 35882577\r\n"
-> "250-8BITMIME\r\n"
-> "250-AUTH LOGIN PLAIN XOAUTH\r\n"
-> "250-ENHANCEDSTATUSCODES\r\n"
-> "250 PIPELINING\r\n"
<- "AUTH LOGIN\r\n"
-> "334 VXNlcm5hbWU6\r\n"
<- "dGhpc2lzbXlAYWRkcmVzcy5jb20=\r\n"
-> "334 UGFzc3dvcmQ6\r\n"
<- "aXRyZWFsbHl3YXM=\r\n"
-> "535-5.7.1 Username and Password not accepted. Learn more at\r\n"
-> "535 5.7.1 http://support.yourdomain.com/smtp/auth-not-accepted nt3sm2942435pbc.14\r\n"

This log shows that the appliance:

  • Opened a connection with the SMTP server (Connection opened: smtp.yourdomain.com:587).
  • Successfully made a connection and chose to use TLS (TLS connection started).
  • The login authentication type was performed (<- "AUTH LOGIN\r\n").
  • The SMTP Server rejected the authentication as invalid (-> "535-5.7.1 Username and Password not accepted.).

Check your GitHub Enterprise Server instance logs

If you need to verify that your inbound email is functioning, there are two log files that you can examine on your instance: To verify that /var/log/mail.log and /var/log/mail-replies/metroplex.log.

/var/log/mail.log verifies that messages are reaching your server. Here's an example of a successful email reply:

Oct 30 00:47:18 54-171-144-1 postfix/smtpd[13210]: connect from st11p06mm-asmtp002.mac.com[17.172.124.250]
Oct 30 00:47:19 54-171-144-1 postfix/smtpd[13210]: 51DC9163323: client=st11p06mm-asmtp002.mac.com[17.172.124.250]

Oct 30 00:47:19 54-171-144-1 postfix/qmgr[17250]: 51DC9163323: removed
Oct 30 00:47:19 54-171-144-1 postfix/smtpd[13210]: disconnect from st11p06mm-asmtp002.mac.com[17.172.124.250]

Note that the client first connects; then, the queue becomes active. Then, the message is delivered, the client is removed from the queue, and the session disconnects.

/var/log/mail-replies/metroplex.log shows whether inbound emails are being processed to add to issues and pull requests as replies. Here's an example of a successful message:

[2014-10-30T00:47:23.306 INFO (5284) #] metroplex: processing <b2b9c260-4aaa-4a93-acbb-0b2ddda68579@me.com>
[2014-10-30T00:47:23.333 DEBUG (5284) #] Matched /data/user/mail/reply/new/1414630039.Vfc00I12000eM445784.ghe-tjl2-co-ie
[2014-10-30T00:47:23.334 DEBUG (5284) #] Moving /data/user/mail/reply/new/1414630039.Vfc00I12000eM445784.ghe-tjl2-co-ie => /data/user/incoming-mail/success

You'll notice that metroplex catches the inbound message, processes it, then moves the file over to /data/user/incoming-mail/success.

Verify your DNS settings

In order to properly process inbound emails, you must configure a valid A Record (or CNAME), as well as an MX Record. For more information, see "Configuring DNS and firewall settings to allow incoming emails."

Check firewall or AWS Security Group settings

If your GitHub Enterprise Server instance is behind a firewall or is being served through an AWS Security Group, make sure port 25 is open to all mail servers that send emails to reply@reply.[hostname].
