makehistory: dbzstore duplicate message-id: what's the consenquences?

[Guich]

Hi,

I got hundreds of warnings like the one in the title.

Reading this:
http://lists.litech.org/pipermail/inn-workers/2003q2/001797.html, i found
that its probably related to cross-post problems.

My question is: is this harmful? What's the consenquences? Will messages me
ignored?

cheers

ps: i'm creating another "how to install INN" very soon to help people
configure.
