JMAP vacation mailet

[Jean Helou <je...@gmail.com>]

Hi,

While playing around with assemblies, I got an error that vacation mailet
configuration was missing when I added the JMAP module
https://github.com/apache/james-project/blob/master/server/container/guice/protocols/jmap/src/main/java/org/apache/james/jmap/draft/JMAPModule.java#L122

I'm not very familiar with jmap and checked a draft at
https://tools.ietf.org/html/draft-ietf-jmap-mail-16#section-1.3
As far as I understand the vacation mailet it is an additional capability
and could thus be made optional, am I correct ?

thanks
jean

Hello Jean,

Sorry for the late answer.

This check was added to ensure the mailetcontainer was correctly
configured to answer people upon vacations.

The JMAP module will require this check, as far as I remember even if
the "JMAP protocol" itself is disabled (likely these checks should not
be performed if the configuration disables the JMAP protocol?)

On the subject of those checks, I personally do not like them yet...
It's a constraint but they are easy to cheat, the security they provide
is limited, but it restrict what as an administrator I could do... Like
re-organizing mailetcontainer.xml to perform a single call to
RecipientIsLocal (and thus to the LDAP) which has a performance and
resiliency impact.

You are right.

Now, does it makes sense to expose the JMAP vacation extension in a
separate Guice modules? Is there some cases we want JMAP but not the
vacations?

By the way allowing people to write their own custom JMAP extensions
might become soon a topic, hopefully ;-)
