## Blacklist email domains
|
||
|
|
|
||
|
|
> [Introduced][ce-5259] in GitLab 8.10.
|
||
|
|
|
||
|
|
With this feature enabled, you can block email addresses of a specific domain
|
||
|
|
from creating an account on your GitLab server. This is particularly useful to
|
||
|
|
prevent spam. Disposable email addresses are usually used by malicious users to
|
||
|
|
create dummy accounts and spam issues.
|
||
|
|
|
||
|
|
This feature can be activated via the **Application Settings** in the Admin area,
|
||
|
|
and you have the option of entering the list manually, or uploading a file with
|
||
|
|
the list.
|
||
|
|
|
||
|
|
The blacklist accepts wildcards, so you can use `*.test.com` to block every
|
||
|
|
`test.com` subdomain, or `*.io` to block all domains ending in `.io`. Domains
|
||
|
|
should be separated by a whitespace, semicolon, comma, or a new line.
