Allow persistent store

[Uni2K]

I wonder if there has been any progress with the persistent store since 2016 and this issue:
[https://github.com//issues/166]

It would be a huge improvement compared to the InMemoryStore.

Any news on the persistent storage ?

Hey @marcelmay!

What do you think of this feature?
Last time this was discussed the requirement was this should be organized as a separate module, and not implemented as part of -core. Do you agree with that?

Thanks and cheers, Balazs

@hosszubalazs ,
how do you intend to use a persistence? I'm asking to understand the use case better.

If you want to avoid message creation in you test code, you could load previously persisted *.eml messages.

IMHO, each test should be isolated - which is why I struggle with persistence.
