[Mailman-Users] Adding old (majordomo) postings to a Mailman archive

[Visvanath Ratnaweera]

Hi all

Before changing to Mailman our list ran on majordomo. I still 
have those postings, in my IMAP mailbox, as a seperate directory.

My question is, how can I add those postings to the running list?

Chronological overlap is minimal. Only for the final month there 
are postings on both sides. Even if I have to delete the ones from 
the old archive, that's not a problem.

regards
