Subject [jira] [Commented] (JAMES-2419) Domain object creation with non printable characters.
Date Mon, 11 Jun 2018 08:04:00 GMT

    [ https://issues.apache.org/jira/browse/JAMES-2419?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16507787#comment-16507787

Matthieu Baechler commented on JAMES-2419:

Good catch.

In my opinion, as *Domain* maps to "domain name in DNS" concept, we should try to comply
to RFCs defining it with maybe restriction when it makes sense.

Wikipedia article [https://en.wikipedia.org/wiki/Domain_name] is a good entry point for that.

>                 URL: https://issues.apache.org/jira/browse/JAMES-2419
>             Project: James Server
>          Issue Type: Bug
>          Components: James Core
>    Affects Versions: 3.0-beta4
>            Reporter: Edgar Asatryan
>            Priority: Major
> Currently it is possible to create *_org.apache.james.core.Domain_* object by supplying
only space (*0x20*) characters. Allowing to create blank domain is at least odd.
> So I divided my question in several parts:
>  * Is it allowed to create *_Domain_* object with
>  ** only control characters?
>  ** control characters in it?
>  ** non ASCII characters?
