# Restrict user email addresses to certain domains
|
|
|
|
{!admin-only.md!}
|
|
|
|
Zulip allows organization administrators to block new users from signing up
|
|
who are not in their organization. The administrator can accomplish this by
|
|
restricting users to have email addresses only from the organization's
|
|
domains.
|
|
|
|
{settings_tab|organization-permissions}
|
|
|
|
2. Restricting user email addresses to certain domains can be enabled or disabled
|
|
with the **Users restricted to (allowed domains)** checkbox in the
|
|
**Joining the organization** section.
|
|
|
|
!!! tip ""
|
|
The allowed domains will be listed after the **Users restricted to**
|
|
next to the checkbox.
|
|
|
|
3. Domains can be added to the allowed domains list by clicking on the **Change domains**
|
|
link next to the checkbox to reveal the **Allowed domains** list. You
|
|
can then add a domain to the list by typing the domain into the box underneath
|
|
the list and clicking the **Add** button.
|
|
|
|
!!! tip ""
|
|
Domains can be deleted from the **Allowed domains** list by clicking the
|
|
**Delete** button next to a domain on the list. However, you must have
|
|
at least one allowed domain if the **Users restricted to** option is
|
|
enabled.
|
|
|
|
5. Once you have made all your changes, exit out of the **Allowed domains** list
|
|
by clicking the x (<i class="icon-vector-remove"></i>) icon in the top
|
|
right-hand corner of the **Allowed Domains** list.
