[jira] [Commented] (JAMES-4171) Submission only server

    [ https://issues.apache.org/jira/browse/JAMES-4171?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18057779#comment-18057779 ] 

Jean Helou commented on JAMES-4171:
-----------------------------------

I think I understand better, do you think it would make sense to keep the behavior separate from AbstractAuthRequiredToRelayRcptHook and introduce a new mandatory SubmissionServerHook which applies this new behavior ? 

> I propose to update the SMTP default configuration to explicitly set authRequired = false on MX to be clearer.

Not sure I understand what you mean but I'll see in the PR :D

> Ideally yes but I'm not in for such a breaking change.

hmm adding a new kind of entry is not a breaking change  but I admit it is probably more work. especially given how the current code parses the configuration

> h3. Context 
> I end up having to provide a submission only server for one of my customer.
> Problem: James bundles together the MX and submission role thus always accept email of remote users addressed to local users.
> This unorthodox behaviour is not a problem when combining both roles (though surprising!) however not being able to say "only authenticated users here" prevents implementing the aformentionned use case
> h3. Proposal
> Add auth.required configuration option in SMTP
> If true, then discard unauthenticated senders.
> This shall be the documented + recommended value however for retro-compatibility I propose to keep the legacy value as a default value.
