The Recipient Restrictions page can be used for imposing restrictions on the recipients users may specify when sending manual or automated emails. To reach this setting, go to the Outgoing Mails configuration tab and choose Recipient Restrictions under the RESTRICTIONS menu item.
Recipient restrictions allow you to hide certain recipient options from every screen where you can select recipients. E.g. if you select Project Roles here, you will not be able to add them as recipients in manual or automated emails. You can filter the following:
- Project Roles
- Groups or Custom Fields.
Restrict recipients in the following way:
- 1.Select the recipient categories in the picker which you want to filter out.
- 2.Enter one or more regexps in the text area.
- 3.Put one expression in one line. The values (project role name, group name, custom field name or custom field id) which match the regexp will be filtered out.
Important: It does not mean that emails will not be sent to member of the selected roles. Same applies to Groups and Fields.
Using regular expressions, limit to or exclude email addresses and email domains when sending emails. Blacklisted recipients may be selected while composing the emails, but they are filtered out during delivery.
To completely remove the possibility to send emails outside your Jira user base, enable this option. Even if email addresses are added to the emails, they will be filtered out during email delivery.
