Outgoing Mail Connections

Unlike Jira, Email This Issue supports the use of multiple Outgoing Mail Connections. To access the list of Outgoing Mail Connections, go to the Administration configuration tab and choose Outgoing Mail Connections under the OUTGOING MAILS menu item.

Built-in Outgoing Mail Connection

Email This Issue comes with a built-in Outgoing Mail Connection that is is available right after installation.
Note: If you use this Built-in Outgoing Mail Connection, emails will always be sent from [email protected]<sitename> . It cannot be changed.
Important: The purpose of the built-in Outgoing Mail Connection is to evaluate Email This Issue and start sending emails right after installation, but we do not recommend it for production use.
We highly recommend you to configure an Outgoing Mail Connection of your choice from a professional email provider such as Google, Microsoft, Yahoo and so on, or use your own corporate Outgoing Mail Connection.

Default Outgoing Mail Connection

One of the Outgoing Mail Connections can be marked as Default. Unless you define to use another Outgoing Mail Connection, the Default Outgoing Mail Connection is used for sending the emails.
You can define the Outgoing Mail Connections to use for different projects, type or issues by creating an Advanced Email Configuration with the proper scope.

Outgoing Mail Connections dialog

Email This Issue supports login and OAuth authentication mechanisms for Outgoing Mail Connections. You can select it by selecting the correct protocol:
  • POP3, IMAP: log in with username and password
  • OAuth for Gmail/Gsuite: OAuth2
The content of the dialog changes based on the authentication method you select.

Microsoft OAuth 2.0 host settings

For OAuth2-based Microsoft365 SMTP connections, the hostname "" is used by default, when connecting to the mail server. However, in certain scenarios, the use of a custom hostname might be required. In such cases, there is a possibility to override the default value by enabling the respective "Override default host setting" toggle and selecting the desired host from the "Host" dropdown appearing below.
The dropdown contains a pre-defined set of hostnames, which are globally available. If you have even more specific needs, please contact our support team.

Shared mailbox settings

A shared mailbox is a mailbox that multiple users can use to read and send e-mail messages. You can read more about them here:​
To use a shared mailbox you just have to enter the email address of the shared mailbox into the From Address field then proceed with the settings as if it was a normal mail account. For the username and password fields (or for the OAuth authorization) use the credentials of the account you want to log in with.

Testing Outgoing Mail Connection

While adding or editing an Outgoing Mail Connection, test if the connection details are correct.

Sending a test email

To check whether the Outgoing Mail Connection is capable of sending out emails to a certain email address, use the Send Test Email function. You can access the Send Test Email dialog by clicking the three dots next to an Outgoing Mail Connection.
