Message-ID's vs. Resent-Message-ID

Thanks, Tomi, for your quick response.

Hmm. Is this a conscious decision, or is the resending case just not taken into account?

What happens if I have both a message and my own copy of it after resending it to somebody else? I would like to have a record of whom I resent it to, as with forwarded messages (where the forwarded message does have a different message id). 

Are the Resent-* headers of the resent message merged into the database entry? I guess this last question is more general: with multiple messages with the same Message-ID but differences (for whatever reason), how will these messages be merged in the database?


Best,

Erik
